WebMost metals undergo plastic deformation when they are subjected to loads beyond their elastic limit. In applications such as metal forming and forging it is important to include … WebThe triaxiality is calculated as the ratio of the first stress invariant and the second one. The Johnson–Cook hardening model is the most well-known viscoplastic strain flow. Their plasticity model considers both kinematic strengthening and adiabatic heating. It describes the dynamic behavior of materials that works in diverse thermal conditions.
