In this paper, we introduce the entropy theory and energy theory into the research of analyzing the crack open and propagation. Regulation, analyzing the factors that affect fractured crack propagation, and establishing the method of researching fractured crack propagation using entropy theory. Transforming the stress factor that affect crack propagation into entropy value, and on that basis we established the entropy variation equation for calculating the crack open, and obtained the new criterion and model for calculating fracturing crack open. Obtaining a new method for describing crack propagation regulation from the entropy aspect. Revealing the nature of crack open, propagation and close from microscope. |
