平面应力(Plane Stress) 特征: σ_{z}=τ_{zx}=τ_{yz}=0 ε_{z} e0 应力-应变公式(Stress-Strain Constitutive Equations):其中, G=\frac{E}{2(1+γ)} --剪切模量(The Shear Modulus) ε_{0} --初始应变(The I…
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...
Equations (11) and (13) – (15) complete the plane strain relations. 8 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...
平面应变的进阶理解 平面应变(Plane Strain)则是在特定条件下，其应力-应变关系与平面应力有所不同。通过替换平面应力公式中的相应参数，我们可以得到如下应力表达式：应力公式 同样，初始应变也会受到热负载的影响，但在这里，假设条件更为特殊：均匀且各向同性的材料，只在弹性形变范围内发生变形。
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=...
