TI - In-plane Crushing Analysis of Cellular Materials Using Vector Form Intrinsic Finite Element T2 - Computers, Materials \& Continua PY - 2010 VL - 17 IS - 3 SN - 1546-2226 AB - The crushing of cellular materials is a highly nonlinear problem, for which geometrical, material, and contact/impact must be treated in one analysis. In order to develop a framework able to solve it efficiently and accurately, in this paper procedures for in-plane crushing analysis of cellular materials using vector form intrinsic finite element (VFIFE) is performed. A beam element of VFIFE is employed to handle large rotation and large deflection in the cell walls. An elastic-plastic material model with mixed hardening rule is adopted to account for material nonlinearity. In addition, an efficient contact/impact algorithm is designed to treat the complex contact/impact encountered in crushed cellular materials. Numerical results performed reveals that the procedures proposed in this paper are sound and reliable to simulate crushing of diverse cellular materials.
