摘要

摘要: 本文应用弹塑性小变形的假定,将应力与应变的关系都用变分形式相联系.简洁地导出板壳塑性屈曲的基本方程,并引入割线模量,计算较方便.

Abstract: This paper gives the stress-strain relations of the variational types on the basis of an assumption concerning the small deformation in the theory of el-asto-plasticity.The compact form of fundamental equations of plastic buckling of the plates and shells is obtained in terms of secant modulus.
