Plastic Deformation - Meaning, Mechanisms and Examples

Webb3 jan. 2024 · Plasticity can be defined as the ability of the materials to get deformed without rupture during the force’s application, which exceeds the yield value of the … WebbWhen deformation is dominated by crystal plasticity, and local cataclastic processes are insignificant, the material is often said to have undergone the brittle-plastic transition. When observed at larger scales, the deformation mode often appears to be “ductile”, meaning that deformation is not localized along a discrete fracture zone.
