Plane stress is a two-dimensional state of stress that occurs in thin structures where the thickness of the material is small compared to the other dimensions. In plane stress conditions, it is assumed that the stress in the thickness direction (usually denoted as the z-direction) is negligible. This is typically applicable to thin plates or shells where one dimension is significantly larger than the other two.
