Difference between the plane stress and plane strain in fracture mecha

1.	Difference between the plane stress and plane strain in fracture mechanics
Answer» Stress is defined as force PER unit AREA. It has the same units as pressure, and in fact pressure is one SPECIAL variety of stress. ... For a 3D system, in PLANE stress condition, thestress in the z-direction is zero. Similarly, in plane straincondition, the strain in the z-direction is zero.
