It is known that the fatigue crack propagation rate is decidedby the stress-strain state of the crack tip at that time. According tolinear elastic Paris relation, this paper has suggested the three-point bendspecimen in which, from linear elastic to overall yielding ragions,da/dNis represented by the retation:da/dN=C_1~r.
