AN APPROXIMATE METHOD FOR DETERMINING THE PLANE STRESS OF ORTHOTROPIC MATERIAL
正交各向异性弹性平面应力的近似计算方法

In this paper, an approximate expression for solving plane stress problem of orthotropic material is worked out based upon the procedures of Lecknitzky's work. For the purpose of applications, three simple examples are given, namely: (1) The bending of beam with circular hole, ( 2 ) circular hole in a plate under simple tension, ( 3 ) elliptic hole in an infinite plane with uniformly distributed pressure acting on the edge of hole.
