- Nonlinear static, dynamic, and thermal finite element analysis of multi-component systems using LLNL suite of analytical software (NIKE2D , NIKE3D, DYNA2D, DYNA3D, TOPAZ2D, TOPAZ3D). Includes modeling of metals (including shape memory alloys--SMA), concrete, composites and honeycomb materials.
- Modeling of multi-piece fastener systems
to determine the influence of various parameters on performance
(e.g., residual preload, joint strength, etc.). The capability
has been substantiated on CherryMAX, Huck-Clinch, Solid Rivets,
Lockbolts, Hi-Loks, All-Max and other fastening systems.
- MMPDS (MIL-HDBK-5) Joint load-deflection behavior. Substantiated for bolted, riveted and blind-fastened flush-fastened joints during Ph.D. research.
- Ballistics modeling, including erosion and element failure. Used during development of latch protective shields used on terrorist-proof cockpit doors.
- Wind load calculation and analysis on
buildings and other structures in accordance with the Uniform
Building Code and ASCE 7-05.
- Runge-Kutta, Newton-Raphson, and other
numerical integration/differentiation tools used successfully
to predict dynamics of decompression latches and panels
in aircraft (substantiated for all single-aisle aircraft
by Boeing, Bombardier, Embraer, and Douglas).
- Conventional structural stress analysis,
including static, fatigue, limit, ultimate, and vibration--using
closed-form solutions ("hand calcs") and/or FEA
- Rapid decompression of pressurized passenger aircraft, including the influence of venting partitions (doors, blow out panels, etc.).
