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 ...
平面应变(Plane Strain) 平面应变 特征: ε_{z}=γ_{zx}=γ_{yz}=0 σz≠0 应力-应变公式(Stress-Strain Constitutive Equations) 替换平面应力公式中的符号: E→E1−ν2 ν=ν1−ν G→G 得出下面应力公式: 应力 其中,由于温度变化,产生的热负载,致使初始应变为: *设定:材料均匀、各向同性...
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...
Strains. The in-plane strain field forms a tensor defined by three independent components: e xx , e yy and e xy . To allow stating the FE equations in matrix form, these components are cast to form a 14–5 Chapter 14: THE PLANE STRESS PROBLEM u = u ^ on Γ u Ω Γ σ ...
known as plane strain.I n view of the stress-strain relations, an equivalent statement to equation (3.1)is and hence a condition of plane strain will exist in a finite cylinder provided that (i) any tractions or displacements imposed on the sides of the cylinder are independent 33 ...

Plane stress is an approximation, as opposed to plane strain, which is an exact solution. 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, ...
