ABSTRACT
Based on the viewpoint that there are similarities to the genetic
principles in the mechanics and the engineering fields; based on data in some
referents and author’s theoretical approach, this paper is to consider the microscopic-damage and the macroscopic-damage
behaviors of materials that
are distinct differences, thereby to propose computing models and methods of
subsection calculations in whole process; to
consider the behaviors between the short cracks and long ones both of which are always continuous, thereby to propose some
computing models and methods of the successive calculations. These computing models refer to formulas of
the threshold sizes of cracks (or threshold values of damages); the propagating
rates of cracks; the predicting calculations of lifetime; Particularly, in which it provides a best new comprehensive figure that it could be including and describing all problems
mentioned above. So it may be as a bridge
to link the traditional material mechanics, the material discipline and the
modern mechanics on fatigue-damage-fracture; perhaps, it can also be as
route diagram to guide designs and calculations to some materials and
structures. Therefore, above
works realize calculations of the strength problems, the growth rate of cracks
(damages) and prediction of lifetime in whole process that would have practical
significances.
