平面应变假定,就是3-D有一个方向特别长,且力的作用方向垂直于长度方向,所以长度方向长到我们可以忽略这个方向的应变( εz=0)。例如重力坝,挡土墙。 平面应力 plane stress vs 平面应变 plane strain编辑于 2019-02-04 08:41 结构工程 有限元分析(FEA) 力学 赞同193 条评论 分享喜欢...
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...
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 ...

Plane strain is a particular solution of the whole three-dimensional elasticity equations, whereas plane stress is only attained in the limit when the thickness of the loaded body approaches zero. Stress, or the force applied to a material, is defined as the force divided by the cross-...
