Finite element analysis of X-cor sandwich´s compressive modulus

Through the analysis of X-cor sandwich´s microscopic characteristics a finite element model of X-cor sandwich´s compressive modulus was proposed. The finite element software ANSYS was used in the computation of compressive modulus. The effects of changing angle, diameter and density on the X-cor sandwich´s compressive modulus were analyzed. The numerical analysis results indicate that as the Z-pin´s angle increases the X-cor sandwich´s compressive modulus decreases, and as the Z-pin´s diameter and density increase its compressive modulus increases. Via the analysis of finite model the influencing trends of X-cor sandwich´s parameters to its compressive modulus are achieved, the rationality of the proposed finite element model is verified and the finite element model can be used to forecast its compressive modulus.
