Experimentally observed crack opening displacements are employed as the solution of the multiple crack interaction problem. Then the near and far fields are reconstructed analytically by means of the double layer potential technique. Evaluation of the effective stress intensity factor resulting from
Interaction of a crack with microcracks (modeiling "damage") can significantly aher the stress concentration at the crack tip. Certain important effects of interaction-shielding effect ("toughening by microcracking"), amplification effect, influence of the orientations of microcracking and irregular
AhstracG-The problems of crack-microcrack interactions and doubly kinked cracks have been analysed by the finite element method. In the first case the main crack tip SIF has been evaluated for different length of a collinear microcrack, which is located at a fixed distance. Through another case stud
