2D Simplification

Contents

• 2D Simplification Options
  

  You can select from four types of 2D simplification options.

• Plane Stress
  

  This option models the problem using a plane stress assumption. A plane stress assumption is valid when one of the principal stresses is so small compared to the other two that it can be neglected. Using this option, you can model thin slabs with one dimension smaller than the other two. The forces acting normal to the section plane should be negligible.

• Plane Strain
  

  The 2D simplification option models the problem using a plane strain assumption. The displacement in one of the directions is neglible compared to the other two. The plane strain condition is valid when:

• Axisymmetric
  

  Use the axisymmetric option when the geometry, material properties, loads, fixtures, and contact conditions have a rotational symmetry about an axis. You can model any cross section about the axis of revolution. If you use multiple bodies, they have to be symmetric about the same axis.

• Thermal Studies
  

  You can use the Extruded or Axisymmetric simplification options for thermal studies.
