Study on the Mechanism Model of Fracture Propagation Based on the Energy Theory

Abstract:

In order to accurately describe the law of fracture propagation, the article, from the energy distribution, presents a new idea about establishing the criterion of crack propagation, explores the regulation of energy changes in the fracture propagation process and then obtains the relevant expression of driving force of fracture propagation. At the same time, it has put the criterion of crack propagation forward with the expression of driving force of fracture propagation, builds the calculation model of crack propagation rates. The calculating result is accurate and agrees well with practical ones
