The main objective of this study was to assess usefulness of 3-D, nonlinear dynamic, explicit computer codes for transit safety and security research. An analysis of response of a paratransit bus structure under loading caused by high explosive (HE) detonation is presented. It was assumed that the cubic HE charge detonates in the air near the bus.

The paper presents finite element (FE) model development and experimental validation for a truck tractor with a three axle single drop lowboy trailer. The main objective of this research activity was to create a simplified, three dimensional virtual FE model, applicable for computer simulation of dynamic interaction between a vehicle and a bridge or road(More)
An extensive validation program was developed and implemented in support of computational mechanics of paratransit buses. The program is based on laboratory testing of coupons for material characterization (test level 1, TL 1) and connection tests (TL 2). Experimental data obtained from TL 1 tests were used for development of the finite element (F.E.)(More)
