Many structural members can be analyzed applying simplifying assumptions of plane stress or plane strain state. Examples include plates under in-plane loading, thick pipes under internal pressure, rotating discs, etc. Although many problems of this type can be solved in a closed analytical form ...

在工程力学中，平面应力(Plane Stress)是一种特殊的情况，其三维示意图揭示了其独特的特性。它的重要公式，应力-应变关系，由以下几个关键参数组成：剪切模量(G)，衡量材料抵抗剪切变形的能力。初始应变(ε₀)，如因温度变化而产生的形变，它反映了物体的初始变形状态。弹性模量(E)，又称杨氏模量...
薄板的中面为平面，其所受外力，包括体力均平行于中面面内，并沿厚度方向不变
PLANE STRAIN AND PLANE STRESS A problem is two-dimensional if the field quantities such as stress and displacement depend on only two coördinates and the boundary conditions are imposed on a line in the I n this sense,there are strictly no two-dimensional problems in elasticity.There are ...
In this article, we explored why we use 2D assumptions, plane strain and plane stress assumptions, and how to choose between them depending on the geometry of interest. Though the development of these mathematical techniques is to facilitate problems, they have applicability to modern engineering co...
For isotropic materials the plane stress and plane strain problems can be mapped into each other through a fictitious-property technique; see Exercise 14.1. Remark 14.2. Transverse loading on a plate produces plate bending, which is associated with a more complex configuration of internal ...
The chapter discusses plane stress and plane strain. The chapter refers to the disk to the orthogonal coordinate system x, y, z explained with a figure where axes x and y lie in the median plane, stress components parallel to the z-axis may be neglected. This equation σ=== 0 is defin...
solutions dates back to the times when many problems were solved by pen and paper, for example, using theAiry stress function, the choice stood in practice between plane stress and plane strain. With finite element software, full 3D or generalized plane strain are better options for thicker ...
