FINITE ELEMENT ANALYSIS FOR MATERIAL NONLINEARITY OF PMI-FOAM CORED SANDWICH

Abstract

Abstract: Based on the provided mechanical property data of the given foam,the nonlinear elastic constitute for this foam is defined． And it is written into a material user subroutine of MSC． Nastran secondary development by Fortran to form the nonlinear analysis model in FEM． An example of foam-cored sandwich aluminum panel is calculated using this method． Through the comparison with the linear analytical,elastic-plastic analytical and experimental results,it demonstrates the accuracy of this nonlinear elastic material finite element model．

Key words: foam core, nonlinear constitute, sandwich structure, MSC．Nastran secondary development
