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 compone
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...
plane strain and plane stress
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...
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-...
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。
