Finite Element Model to Reduce Fire and Blast Vulnerability

Finite element models of the generic V-Hull and soldier were successfully integrated. Methodologies were developed to investigate the effects of structural component variations and safety measures on the risk of injury to the legs and lumbar. These models and software tools can now be used by the Army to evaluate future designs and improve current vehicle designs in an effort to improve occupant safety on and off the battlefield. Studies were performed to investigate the effects of material thickness on the lumbar and legs during an underbody blast event. A study was completed that determined the effects of foam on tibia forces during an under body blast event.
