Cellular foams play a critical role in engineering today (automotive, aerospace, civil, and protective equipment applications) due to their high energy absorption and lightweight nature. Using foam enable the development of design solutions that optimize safety, performance while keeping weight to a minimum, ranging from collision management systems and acoustic damping to packaging and occupant protection. This work focuses on polyurethane foams used in high-voltage battery pack crash protection Despite their widespread use, accurately predicting foam behavior under loading conditions is challenging. The highly nonlinear, rate- and temperature-dependent response, important tension/compression asymmetry and volumetric effects introduce complexities that are not fully captured by classical models.
