Plane Stress Elements

They must be plane, i.e., the coordinates of the element nodes must be in one flat plane, the xy plane of the element. They must be thin, i.e., the thickness t must be small in relation to the dimensions b in the plane of the element. Loading F must act in the plane of the element. Plane stress elements are characterized by the fact that the stress […]

They must be plane, i.e., the coordinates of the element nodes must be in one flat plane, the xy plane of the element. They must be thin, i.e., the thickness t must be small in relation to the dimensions b in the plane of the element. Loading F must act in the plane of the element.

Plane stress elements are characterized by the fact that the stress components perpendicular to the face are zero:  = 0 . These elements may only be applied if there is no bending outside the plane of the structure, like in walls, deep beams and the like.
