Abstract

The fatigue crack development regularities under working load simulation have been studied. The fatigue crack development pre-threshold region has been investigated. The level decrease method of irregular working load with similarity preservation has been applied. This is achieved with the test sample suppleness increase by a crack extension in it. Experimental dependences of the crack development rate on the number of working load blocks at its level decrease have been obtained.
