Abstract

To use the theoretical approach, to adopt the multiplication-method of two-parameters, by means of the traditional and the modern material constants, thereby to establish some of new calculation models in all crack growth process. In which are the equations of the driving forces, the crack-growth-rate-linking-equation in whole process, and the life predictions; and to propose yet some calculating expressions under different loading conditions. For key material parameters give their new concepts, and provide new functional formulas, define their physical and geometrical meanings. For the transition crack size from micro to macro crack growth process, provide concrete calculation processes and methods. Thereby realize the lifetime predicting calculations in whole process based on conventional materials constants and by the multiplication method of two parameters.
