2D Plane Stress Structure Model Type

Use this option if you are modeling a thin, flat plate—for example, a piece of sheetmetal under tension. In 2D plane stress models:

• All included geometry must lie in the XY plane of the Cartesian coordinate system that you select as the reference coordinate system for your model. If you are working with assemblies, all included geometry from the assembly components must lie at the same Z depth.

• Loads and displacements must be in the XY plane.

For 2D plane stress models, Creo Simulate meshes your model using 2D plate elements. To successfully run an analysis, you must first assign a simple or advanced shell idealization to any surfaces you plan to include in your plane stress model. In addition to the shell idealizations that you must assign, you can create the mass and spring idealizations for a 2D plane stress model.

As mentioned, you must use a Cartesian coordinate system as the model type reference coordinate system. However, you can base other modeling entities on Cartesian, cylindrical, or spherical coordinate systems. You can define loads, constraints, and other model attributes in two degrees of freedom for a plane stress model—translation in X and Y (or the cylindrical and spherical equivalents).
