✦ Synopsis

An equation is derived that describes the rate of growth of fatigue cracks under combined static and cyclic stxesses. The equation predicts that a static tensile stress has very httle influence on the rate of growth of fatigue cracks, even ff the static stress is very much larger than the amplitude of the cyclic stress, unless the maximum total applied stress is comparable to the (statac) fracture stress.

* This prediction and experiment82 support for it already appears in the literature [5][6][7]. The reviewer is thanked for pointing out this fact.

## Abstract In this paper a procedure to simulate the crack growth under consideration of elastic‐plastic material behavior by means of the finite element method is described. Within this procedure, after each increment of crack advance, the structure is remeshed and the status variables, such as t
