摘 要: | 本文从弹性体的三维 L—N方程出发,导出了平板问题的普遍形式解.作为实例,给出了半无限板、半无限长板条两个边值问题的严格解析解.用本文的方法分析平板,所得结果能反映边界位移和应力沿厚度方向的变化情况.

Abstract: | In this paper,a general solution for plates is derived from 3-D L-N equations of elastic body.As examples,two boundary-value problems of a semi-infinite plate and a semi-infi- nite strip are formulated.The variations of boundary stresses and displacements along the thickness of plates are reflected in the present method. |
