Finite element analysis of low-density high-hysteresis foam materials and the application in the automotive industry

摘要

A new foam material model has been developed incorporating both theoretical formulation for low-density high-hysteresis foam and test data. Detailed formulation is presented. The finite element analysis of the resilient bumper and IP head impact are also discussed. A good correlation is concluded by comparing the results from the tests and the FEA simulations.
