Determination of crack initiation direction from a bi-material notch based on the strain energy density concept
The article presents a procedure for the determination of the direction of crack initiation from a bi-material notch based on knowledge of the strain energy density distribution. First, the strain energy density for a bi-ma...

Measurement of local initiation, early growth and retardation of physically short fatigue cracks using amended DCPD method.
The aim of the work described in this paper was to explore possibilities and limits of the use of DCPD (direct current potential drop) method for physically short crack measurement and to use the optimised method for an evaluation o...
