Finite element calculation for comparison of compression resistance of different core reinforced materials

In order to analyze the effect of different core materials on the compression resistance of the Oshaped core reinforced composites,the mechanical responses of three kinds of core materials of resin core and glass-fiber core as well as metal core reinforced composite under the same compression action were compared by the calculation using finite element analysis( FEA). By comparing and analyzing indexes of deflection-time curves,weight,stress distribution,and equilibrium degree of stress,it was found that both of the stress distribution symmetry and loading equilibrium were beneficial to the loading-bearing performance of the materials, even which can absorb more energy and generates relatively-small deformation. Furthermore,taking the requirements of compression resistance,loading equilibrium and light-weight into consideration,the glass-fiber core reinforced composite should be selected instead of resin or metal core reinforced composites.
