Plastic strain introduction

Any object will deform under the action of external force. When the deformation does not exceed a certain limit, the deformation energy will disappear after the external force is removed. This deformation is called elastic deformation. If the external force is large, when its action stops, the resulting deformation does not completely disappear, but there is residual deformation, called plastic deformation.
