Microstructural-dependent nonlinear stability analysis of random checkerboard reinforced composite micropanels via moving Kriging meshfree approach

In the present study, through matching the moving Kriging meshfree formulations with the third-order shear flexible shell model together with the modified strain gradient continuum mechanics, the microstructural-dependent nonlinear stability behavior of micropanels under axial compression is explored. The micropanels are made of composites containing graphene nanoplatelets dispersed in random checkerboard pattern. The associated material...
