Elastic-plastic material behavior
WebIn exact analyses of bodies in the elastic–plastic regime, the behavior of the material above critical stress values plays a key role. In addition, under cyclic stress, important phenomena to be taken into account are the various types of hardening and the design of the material or structure. In this process, it is important to define several groups of … WebGenerally, the terms ‘plastic’ and ‘elastic’ are, physical properties, used to describe an object. They describe the attributes of materials such as rubber, plastic, metal, etc. In physics, when an external force is applied to the surface of any material or a body, the material undergoes a physical change or deformation.
