| Abstract: | Summary In this paper, the curved-crack problem for an infinite plate containing an elastic inclusion is considered. A fundamental
solution is proposed, which corresponds to the stress field caused by a point dislocation in an infinite plate containing
an elastic inclusion. By placing the distributed dislocation along the prospective site of the crack, and by using the resultant
force function as the right-hand term in the equation, a weaker singular integral equation is obtainable. The equation is
solved numerically, and the stress intensity factors at the crack tips are evaluated. Interaction between the curved crack
and the elastic inclusion is analyzed.
