Finite Element Crash Analysis of a Rear-Engine Automobile

A finite element model of a rear-engine automobile having a fiberglass-reinforced resin body, was created and examined in a 30 mph frontal barrier impact analysis using the DYCAST nonlinear structural dynamic finite element computer code. Detailed results were produced, including load paths, material failures, and behavior of individual components, permitting an assessment of vehicle crash performance. A proposed energy-absorbing concept was evaluated and recommendations were made for specific structural improvements.
