Abstract
A study is undertaken into the kinetics of phase transitions in solids under a load at a fixed temperature. The critical size of the micropores forming at a given load in the course of a phase transition in a material is found. The steady-state flux of pores in size space and the time required to reach this state, which depend at a given load on the surface energy of the solid and on an additional parameter characterizing the boundary kinetics of microdefects, are calculated. The parameters found in this work, which describe the onset of the latent stage in the fracture of a solid and the intensity of defect formation in the material in this stage, are new in the mechanics of fracture. This approach allows generalization to load-induced structural and martensitic transitions.
