平面应变(Plane Strain) 平面应变 特征: ε_{z}=γ_{zx}=γ_{yz}=0 σ_{z}\ne0 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、...
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 states of plane stress and plane strain, for material stretched along x, are illustrated. Example The illustrated device stretches a thin sheet of material while holding the width constant. The sheet is 10 mm thick, and is linearly elastic with Poisson’s ratio ν = 0.3. if the pulling...
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 ...
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 ...
STRESS-STRAIN BEHAVIOR OF SAND IN PLANE STRAIN COMPRESSION, EXTENSION AND CYCLIC LOADING TESTS Stress-strain behavior of sand in plane strain compression, extension and cyclic loading was studied. To attain plane strain extension stress states in a c... MASUDA,TORU,TATSUOKA,... - 地盤工学会...
5.2 Plane stress and strain 5.2.1 In-plane stresses Sign convention and units In Fig. 5.1, the state of plane stress at a point of an elastic body is represented by two normal stress components (σx, σy) and one shear stress component (τxy), which act on four sides of an element...
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-...
abaqus中设置section的时候plane stress/strain thickness是平面应力应变单元的厚度设置。一、 部件 创建2D平面部件，造轮，命名为Prat-1。创建部件，造轴，命名为Prat-2。创建部件，造键，命名为Prat-3。二、 性质 1、 创建材料：将材料命名为Material-1，可以自选不同材料，也可以用：E=210GPa，ν=...
