FINITE ELEMENT SIMULATION FOR THE PLASTIC BEHAVIOR OF CORRUGATED CORE SANDWICH PANEL

Abstract

Nowadays, numerical simulation methods have been widely applied in product design and development, especially in sandwich panel design. However, such numerical models need to be built to optimize calculation time. In this paper, we propose a finite element model to study the plastic mechanical behavior of corrugated sandwich panels. Accordingly, a 2D finite element equivalent model is built by the homogenization method to replace the 3D model. This model greatly reduces the computation time as well as the model building time. The accuracy of the proposed model is confirmed by comparing the numerical simulation results of the 2D equivalent model with the 3D model and experimental results.
