基于三阶剪切变形理论及径向基函数,预测弹性板的临界荷载。该理论说明了沿钢板厚度方向的横向应力呈抛物线分布的原因。结果表明:径向基函数能精确地预测钢板的临界荷载和失效模式。
Prediction of Critical Load of Elastic Plate Based on Third - Order Shear Deformation Theory and Radial Basis Function. This theory shows the reason that the lateral stress along the thickness of the steel plate is parabolic. The results show that the radial basis function can accurately predict the critical load and failure modes of the steel plate.
