โœฆ Synopsis

The torsional impact response of a penny-shaped crack lying on a bimaterial interface is considered in this study. Laplace and Hankel transforms are used to reduce the problem to the solution of a pair of dual integral equations. The solution to the dual integral equations is expressed in terms of a Fredholm integral equation of the second kind with a finite integral kernel. A numerical Laplace inversion routine is used to recover the time dependence of the solution. The dynamic stress intensity factor is determined and its dependence on time and material constants is discussed.

The transient response of a pressurized penny-shaped crack subjected to a time-dependent load is considered. The crack is embedded in an elastic-plastic solid and the plastic zone has the shape of an annulus of small thickness surrounding the crack and extending radially. The Dugdale hypothesis is a
