Summary
This paper contains an analysis of interaction of torional waves normally incident on a rigid circular disc located in an infinite elastic cylinder. The cylinder is bonded with an infinite medium. Both the infinite cylinder and infinite medium are of dissimilar materials, homogeneous and isotropic. The solution of the problem is reduced into a Fredholm integral equation of the second kind. The numerical solution of the Fredholm integral is obtained. Numerical values of the stress intensity factor at the rim of the circular disc have been been obtained.
