摘要: Abstract Geometrical softening is possible in shear if the solid contains voids, flow becoming localized between voids. Flow localization may also be caused by quasi-adiabatic thermal along bands. Experimental instabilities result from either cause, depending on void nucleation strain, volume fraction of pressure dependence hole growth rates, work hardening index and a characteristic material parameter M reflecting thermomechanical properties solid. Second are where two causes act together. It shown that data strain which considerably over-estimated thermoplastic theory readily explained isothermal geometric presence
