A two-dimensional plate theory is derived for incompressible transversely isotropic fiber-reinforced materials with wavy fibers. Single-layer plates and two-layer laminates are considered. Numerical simulations of axially loaded rectangular sheets in the post-buckling regime illustrate the marked effect fiber waviness has on both the wrinkling patterns and the effective axial stiffness. For fibers oriented along the loading axis, increased waviness tends to decrease the axial stiffness. Conversely, for fibers oriented transverse to the loading direction, increased waviness tends to increase stiffness.

波浪形不可压缩各向异性薄板起皱的模拟

对于波浪形纤维，不可压缩的横向各向同性纤维增强材料推导出了二维板理论。考虑单层板和两层层压板。后屈曲状态下轴向加载的矩形薄板的数值模拟表明，纤维波纹度对起皱模式和有效轴向刚度都有显着影响。对于沿加载轴取向的纤维，增加的波纹度倾向于降低轴向刚度。相反，对于横向于加载方向取向的纤维，增加的波纹度倾向于增加刚度。
