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