  If the strain state at a material particle is such that the only non-zero strain components act in one plane, then the particle is said to be in plane strain. This option assumes that there is zero strain in perpendicular direction.

  Hi @skadam - When can we set 2D behavior as plane strain for a shell body?

  Hello @akhemka , that is good question!!
  You can use this behavior when the dimension in the Z direction is very large compared to X and Y dimensions for a body. The stress in Z direction is non-zero. When you have long, constant cross-section for the body, you can use plane strain behavior.

  Hey, one important thing to note, we can not use plane strain for thermal analysis.

  Please Help. if i want to simulate tyre deformation in a 2D cross section, further i want to make the 3D model using a revolve. In the 2D analysis should i consider the "Plain Stress" or the "Plain Strain" ?
