..., it is. Localized Deformation: The plastic deformation in ISF is localized; that is, the plastic zone is always embedded in the surrounding material, which behaves elastically and supports the forming zone. This can have important effects on the development of a localized neck. Cyclic Deformation: As shown...

Once initiated, the fatigue fracture can propagate by high stresses and low cycles or by low stresses and high cycles. The final rupture may have characteristics of brittle and/or ductile fracture modes, depending...

..., they exhibit mechanical hysteresis. This is due to the energy-dissipative nature of these materials when they undergo cyclic testing. Thus, some of this inelastic deformation energy is transferred into heat. With each cycle, heat buildup raises the temperature of the specimen. A plastic material heating up...

Ductile fracture often occurs with the material undergoing yielding and plastic deformation. Brittle fracture occurs as an unstable event where the crack propagates...
