✦ Synopsis

The objective of the present paper is to study the fatigue propagation behaviour of two parallel edge-cracks in a finite width sheet. By using the stress intensity factor relation proposed by the authors, experimental data are analysed and the influence of geometry of edge-cracked sheet on crack growth rate is discussed. The applicability of the maximum dilatational strain energy density criterion, T-criterion, as proposed by Theocaris and Andrianopoulos, is investigated for use in a crack propagation angle study.

Using the scanning electron microscope, fatigue striations in secondary microcracks normal to the main fatigue cracks have been observed on fracture surfaces of fatigue specimens made from 2024 and 2618 aluminium alloys, a Ti-6AI-V titanium alloy, and an Incolloy 901 nickel-base refractory alloy. Te
