Inner Variable in Crack Healing Processing

-
Abstract
According to the thermodynamics of continuous medium, the dissipation inequation of crack healing is derived from the second law of thermodynamics. An inner variable H is defined which describes the process of crack healing. Based on variable H , the crack healing process can be explained, the evolutionary equation and constitutive equations of the process can be established, and thus it is possible to analyze the process quantitatively.
