1. Provided on-site structural analysis support to Airbus America Engineering (AAE) Fatigue & Damage Tolerance Group in Wichita.a. Produced detailed finite element (FE) models and conducted FE analysis for A380 parts using Patran and Nastranb. Performed FE model data check per AAE specificationsc. Compiled technical reports upon task completion2. Simulate and Predict Failure Strengths and Allowables Development Process of Composites Phases I & IIa. Used micromechanical equations to reverse engineer constituent properties for composite materialsb. Developed a multi-scale analysis methodology and provided guidance for generating mechanical properties for composite materials using micromechanical material modelers such as Helius and Digimat. Validated the methodology and benchmarked analysis modelsc. Demonstrated the ability of FE models to predict most mechanical properties (within 10% of tested properties)d. Investigated variability in composite materials due to manufacturing and incorporated the variability into virtual simulationse. Used optimization tool along with micromechanical material modelers and UMAT user subroutine in finite element analysis to virtually generate A and B-Basis allowables according to CMH-17 Handbook for composite materials used in general aviation. Virtually generated material allowables were comparable to values obtained from NCAMP multi-batch test dataf. Developed VBA codes to create FE modelsg.
