In order to predict the bearing capacity of composite laminate with different fiber angle-ply and different elliptical cutout geometry parameters

commercial finite element software package was employed.Through varying fiber angle-ply and geometrical parameter of cutout

the law curve is obtained.The results show that buckling loads of(0/90)4 and(-45/45)4 are in symmetry with elliptical rotation angle θ=45°

but the(-15/75)4 and(-30/60)4 are in asymmetry with θ=45°.This is due to the fiber angle-pl...
