摘要: Given that the plastic state of substances is similar to liquid state, work deformation assumed be proportional heat melting. An equation derived which relates dynamic elastic limit volume change upon “mechanical melting.” The proportionality coefficient in this determined by degree fragmentation crystalline grains (shock-compression rate). use microscopic atomic rigidity characteristics makes it possible derive a universal formula for calculating with reasonable accuracy.
