Abstract

The author bases on the principles of similar to the genetic genes in the life sciences, discovers some new constants shown material properties from a short crack to long crack, and proposes some new computing models which are the calculable length of a crack, the threshold size and the critical ones on crack problem to some metallic materials; which are to use the theoretical approach, to adopt the conventional material constants, to derive the new mathematical models and the stress factor of called crack strength, to provide simple assessment criterions on the crack strength and the calculating methods in each stage. In addition, supplements again the comprehensive figure of the material behaviours; gives yet a detailed calculating example for a safety assessment.
