摘要:
AbstractDimensional analysis has been applied to the fatigue failure of a material. The growth rate of cracks propagating within the limitations of LEFM can be described unequivocably by ΔK, as for example, in the Paris law. However, in the more general case, when LEFM conditions are violated or when the crack is short, an extra term, relating plastic zone size to crack length, is needed to preserve the physical similarity
