Thota, N. M. and Epaarachchi, J. A. and Lau, K. T. (2013) Important aspects of finite element modeling of low density thermo plastic closed cell foams. In: 3rd World Congress on Frontiers of Mechanical, Aerospace and Automotive Engineering (WCFMAAE 2013), 2-3 Feb 2013, New Delhi, India.


Finite element modeling of low density, highly compressible, thermo plastic elastomeric (TPE) foam is a challenging task and it requires appropriate material data and various parameters to run the simulations without premature termination. For nonlinear, transient dynamic simulations, a commercially available CAE software LS-DYNA was used. For modeling of the foam projectile, a material model MAT_057 (MAT_LOW_DENSITY_FOAM) was considered. Finite element convergence study and various parameters of the material data for completing the simulation run without any errors are presented in this paper.
