Current Research

Nonlinear dynamic finite element analysis: Methods to improve dynamic nonlinear finite element analyses of aircraft and spacecraft structures for severe landings and crashes onto soil, hard-surfaces, and water are being researched.   Better dynamic models of aerospace materials, including layered composites of carbon and Kevlar, and covering the regimes from elastic through plastic to failure including rate effects are a particular concern.

Human and human surrogate impact tolerance:  Limitations of human injury risk criteria used to estimate the severity of occupant injury and survivability for aerospace vehicle impacts are being evaluated.  Both physical crash test dummies and test dummy math models for multidirectional impacts are investigated.  Aircraft crashes subject occupants to vertical impact forces that are rarely seen in automotive crashes
