Abstract

The problem of torsional impact response in an infinite cylinder with a circumferential edge crack is solved. Using Laplace and Fourier transforms the problem is reduced to a singular integral equation of the first kind that has Cauchy-type, logarithmic and generalized Cauchy-type singularities. The kernel of the integral equation is improved in order that the calculation may be made easy. Dynamic stress-intensity factors are estimated with good accuracy.
