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 ...
1.1.18 2D problems If a structure is long, and a uniform stress is applied in the perpendicular direction to the structure boundary, the displacement in each section is expressed with a function of x and y. It is called as a plane strain problem. The displacement is expressed by: ui=ui...
In this article, we explored why we use 2D assumptions, plane strain and plane stress assumptions, and how to choose between them depending on the geometry of interest. Though the development of these mathematical techniques is to facilitate problems, they have applicability to modern engineering co...
PLANE STRAIN AND PLANE STRESS A problem is two-dimensional if the field quantities such as stress and displacement depend on only two coördinates and the boundary conditions are imposed on a line in the I n this sense,there are strictly no two-dimensional problems in elasticity.There are ...
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...

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。
