Localization of adiabatic shear bands in an AZ31 magnesium plate under loading by a punch
摘要
Using the method of numerical simulation, the formation of localized adiabatic shear bands in the sheets made of AZ31 magnesium alloy is studied by dynamic punching at the following velocities: 10, 25, 50 and 100 m/s. The computations involve the alloy material fracture, using the critical level of specific energy of shear deformations as a fracture criterion.
