新一类各向异性叠层板弯曲近似方程

A New Approach to the Bending Equation of Anisotropic Laminated Plates

利用初始函数法，提出一种类似三阶位移模型的板弯曲方程新模型．本模型对应力和位移不作任何假设并考虑到层间应力和位移的连续性，它不包含任何模型误差，只含有近似阶误差．计算表明，它较三阶位移模型有更好的精度．

A new model of plate bending Similar to the model of three-order displacement is proposed by means of the method of initial functions. The model putS no assumption on stress and displacement and tubes into account the continutity of interlamellar Stress and displacement.It contains not any error of the model but only error of approximate order.It is indicated by numerical calculstion to be more precise than the model of three-order displacement.
