Analysis of three-dimensional interface corner cracks

© 2019, Faculty of Mechanical Engineering, Belgrade. The growth of an interfacial crack, from the straight corner along the joint plane between the two long plates made of different materials is considered in this paper. Three different shapes of the crack front are analyzed: the concave, triangular and the quarter circular shape. Results are presented for variations of the normalized stress intensity factors of all the three crack loading Modes, As well as the normalized phase angles and the normalized energy release rate, all in terms of an angle, which measures the distance from the symmetry plane
