IMPACT

The computational modeling of crush, crash and impact events is a large field of research, which is critical to engineering analysis. Generally, impact corresponds to high speed and high energy events, which may require high strain rate material characterization. In order to conduct a validated test, all cases require true multi-scale analysis in order to accurately predict structural behavior subject to combined loads and multiple active failure mechanism.

GENOA’s PFDA module can do that.

GENOA Progressive Failure Dynamic Analysis (PFDA) augments explicit dynamics finite element analysis (FEA) with multi-scale progressive failure analysis of composite structures. GENOA PFDA produces an integrated explicit dynamics solution stimulating all five stages of impact. With the ability to track fractures to determine all stages of damage evolution. GENOA also calculates crack density, micro-cracks delamination, and fiber failure and compression including micro-buckling.
