The in-plane loading of rigid disc inclusion embedded in a crack

The paper examines the in!plane loading of a disc shaped rigid disc inclusion which is embedded in bonded contact with the plane surfaces of a penny!shaped crack[ The mixed boundary value problem governing the elastostatic problem is reduced to the solution of a system of coupled integral equations\ which are solved numerically to determine results of engineering interest[ These results include the in!plane sti}ness of the disc inclusion and the crack opening mode stress intensity factor at the boundary of the penny!shaped crack
