- Description
- NASA/GRC plans to issue a Request for Quote (RFQ) for Performance Based Task Order Description: The Contractor's work shall involve software code development of the CARES/MEMS (Ceramics Analysis and Reliability Evaluation of Structures for Micro-Electro-Mechanical Systems) program. This effort is an outgrowth from the CARES/Life program for reliability analysis of bulk monolithic ceramic structures. CARES/MEMS will be a dedicated version of CARES/Life tailored to the unique challenges of MEMS devices. The Contractors shall prepare and release updates (as needed) of the CARES/MEMS program to American industry, publish the results of related advancements in research publications and give oral presentations to appropriate NASA staff and technical communities. The contractor will also assist in experimental verification activities regarding MEMS reliability modeling methodologies in cooperation with NASA GRC Life Prediction Branch (Org. 5920) and the Sensors and Electronics Technology Branch (Org. 5510). This work seeks to examine the stochastic strength behavior of brittle MEMS materials at appropriate size scales, and to test the viability of using the Weibull distribution to model such devices. The information obtained could be used to help assess the integrity and durability of sensors and micro-engines/rockets. This effort will also help establish greater understanding of the mechanisms responsible for the stochastic strength behavior in MEMS devices, and to test the viability of using the GRC program CARES/MEMS under development. Expertise and prior history shall be provided by the bidder in the disciplines required to successfully complete the CARES/MEMS project. Proof of level of expertise and experience is requested from the bidder by providing NASA a list of technical publications/reports and contracts of work performed in these areas (item 1 to 5 below). The bidder shall have knowledge and experience in: 1. Batdorf statistics for multiaxial loading of brittle isotropic materials. The bidder shall have knowledge of Batdorf methodology and how it extends to proof testing, grinding damage, and anisotropic materials. Further and foremost, the bidder shall be familiar with this methodology as applied to transient loading situations as a function of time/temperature where Batdorf, Weibull, and fatigue parameters can vary with time/temperature. The bidder also shall be familiar with how slow crack growth and fatigue are incorporated into the Batdorf methodology. The bidder shall be familiar with the normalized Batdorf Crack Density Coefficient, how its computed, and how it's applied to component reliability analysis. The bidder also shall be knowledgeable in Weibull, Batdorf and fatigue parameter estimation techniques from specimen rupture data from generalized component geometries. 2. The bidder shall be intimately familiar with the NASA CARES/Life computer program. Both in the use of the program and in its programming. The bidder shall be familiar with the CARES/Life numerical algorithms both for component time-dependent reliability prediction as well as parameter estimation (Weibull, Batdorf, and fatigue parameters). 3. The bidder shall be intimately familiar with the FORTRAN and Delphi computer languages. 4. The bidder shall have expertise with the ANSYS and ABAQUS finite element programs such that they can write and debug custom written macros written in the base languages (example for ANSYS is APDL - ANSYS Parametric Design Language) of these software packages. 5. The bidder shall be familiar with structural MEMS (MicroElectroMechanical Systems) issues - such as testing methods and data analysis techniques. THE CONTRACTORS SHALL PERFORM DUTIES AS INDICATED BELOW: 1. Complete the development of FORTRAN based coding that will function as an input/output (I/O) interface to existing (partially developed) transient reliability analysis subroutines and existing (within WinCARES version 5.2) Weibull and Fatigue parameter estimation subroutines (developed at GRC). The transient reliability coding must span both Batdorf and PIA (Principal of Independent Action) based analysis. This code must be capable of reading a specified format (neutral data base) of transient finite element analysis results and outputting component reliability at user specified time steps. The new capabilities of single crystal transient reliability analysis and transient proof testing is also to be included. The time-dependent transient reliability analysis capability must include formulations for power law, Paris law, Walker law, and a superposed (combined) power and Walker law life prediction capability. The contractor is responsible for modifying and extending the GRC supplied numerical algorithms with the new capabilities outlined in this statement of work. Output features must include element risk-of-rupture data files formatted for ANSYS, PATRAN, and IDEAS import. Additional I/O features should include user-selected outputs of element stresses, properties, and reliability as a function of time steps. Capability to perform reliability analysis on multiple concurrent flaw populations simultaneously is required for both volume flaw and surface flaw based criteria. Additional I/O functionality is required to account for cyclic symmetry (component geometry multiplication) reliability analysis and multiplication of element stresses by a user defined factor. The parameter estimation and component reliability analysis capability need to work seamlessly (must be interoperable) such that results from parameter estimation are made directly available to the component reliability analysis module. A text based input format controlling the CARES/MEMS program must also be developed. This input structure will consist of mutually agreed upon (Between Contractor and NASA) keywords in a free-field input format style that controls the overall function of CARES/MEMS. The delivered FORTRAN code must be of a quality level such that it can be released to US based organizations for beta testing. The code needs to be in a modular format so new capabilities are easily added - such as I/O for single crystal reliability analysis. Documentation regarding keywords, input arguments, program setup, and program operation must also be included in the form of a user's manual. 2. Develop in cooperation with NASA, FORTRAN coding for a single crystal reliability model for cubic crystal systems consistent with single crystal silicon and single crystal silicon carbide. This capability must include time-dependent transient reliability analysis with proof testing. The anisotropic reliability modeling methodology will be specified by NASA. This item must operate with item (1) above and item (4) below and have a simplified input structure for easy selection by a user. 3. Develop in cooperation with NASA, FORTRAN coding for edge flaw reliability analysis of a component. This methodology will be a simplified PIA formulation of a single stress component. The reliability modeling methodology will be specified/provided by NASA. Again, this includes the capability for time-dependent transient reliability analysis. Also, develop FORTRAN coding to determine the Weibull scale parameter of edge flaw data from tensile and 3- and 4-point flexure specimen rupture data. The parameter estimation methodology will be specified by NASA. This item must operate with item (1) above and item (4) below and have a simplified input structure for easy selection by a user. 4. Complete the development of the Windows based GUI for item (1) above incorporating transient analysis and parameter estimation capabilities. The GUI will be an enhancement/replacement of the existing CARES GUI. This GUI will include an interface to the Weibull and fatigue based parameter estimation, the PEST module of CARES/Life (WinCARES version 5.2). It will also be capable of working with ANSYS ABAQUS, and MARC files/databases to create CARES/MEMS compatible neutral data files of finite element analysis results. NASA will supply FORTRAN based algorithms that create the CARES/MEMS compatible neutral file database from ANSYS, ABAQUS, and MARC, files/databases. The contractor will be responsible for modifying these FORTRAN codes into a finalized neutral data file format and making them interoperate with the CARES/MEMS GUI. The GUI will be based on the Delphi language (and software) from the vendor Borland. The GUI will allow the user control over individual input items to the CARES/MEMS FORTRAN code for both component life prediction and parameter estimation. The GUI will prepare text based input files in the format prescribed for item (1) above. The GUI will also display results from analysis. 5. Prepare simplified users manual of CARES/MEMS including example/benchmark problems demonstrating CARES/MEMS capabilities. These can be simple or complex component geometries at the discretion of the contractor. This must include a demonstration of edge flaw and single crystal reliability analysis capability. The ANSYS edge flaw recognition macro developed previously for NASA must be demonstrated to work in the prepared example problem. All example/benchmark problems must be sufficiently documented such that a 3rd party user can understand, duplicate, and apply these capabilities to other MEMS components. 6. Complete a test matrix for the design of experiments of square and round pressure membranes of various materials. This requires detailed finite element modeling of the membrane and support structure in order to properly model areas of high stress. CARES/Life will be used to calculate effective areas of the films to examine a hypothetical Weibull size effect between the different geometries for Weibull modulii of 5.0, 10.0, 15.0, 20.0, and 25.0. Hypothetical 90% confidence intervals on the Weibull characteristic strength will be determined for the various Weibull modulii and specimen geometries. This analysis will enable the fabrication of test specimens (by NASA) appropriate to test the Weibull size effect hypothesis. The analysis will also be used to help determine what pressure levels are required to cause rupture in a pressure rig. 7. Cooperate with Johns Hopkins University (JHU) in the reliability analysis investigation of straight, notched, and holed, microtensile beams for evidence of Weibull size effect. The contractor shall be responsible for designing a microtensile specimen geometry of a geometry that yields an intermediate effective area (intermediate Weibull size effect) between a notched and straight-sided specimen geometry. The design must be compatible with the existing JHU microtensile specimen testing rig. The contractor shall subsequently perform reliability analysis in conjunction with finite element analysis using results of fracture stresses of the various specimen geometries (fracture stress data provided by JHU). The contractor will participate in co-authoring a technical paper with NASA and Johns Hopkins researchers regarding this work (item 7). 8. Participate in co-authoring a technical paper with NASA personnel regarding newly developed transient reliability analysis capability. This work assignment requires expertise in FORTRAN and Delphi programming languages as well as expertise with finite element analysis software and use (and programming) of the CARES/Life program.
