Further, the stresses, , and are all zero for this kind of geometry and loading. The non- zero stresses, , and lie in the X-Y plane and do not vary in the Z direction. Let the X-Y plane be the plane of analysis. However, two-dimensional models are often easier to develop, easier to solve and can be employed in many situations if they can accurately represent the behavior of the object under loading.Ī state of Plane Stress exists in a thin object loaded in the plane of its largest dimensions. In general, the analysis of such objects requires three-dimensional modeling. When referenced to a Cartesian coordinate system these components of stress are: It is possible for an object with arbitrary shape to have six components of stress when subjected to three-dimensional loadings. Using the various ANSYS 2D element formulations.Evaluating potential errors in the solutions.Solving planar stress concentration problems.The tutorials in this lesson demonstrate: Plane s1ress and plane strain problems are an important subclass of general three- dimensional problems.
