โœฆ Synopsis

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 applied to find the length of the plastic zone as a function of the applied time-varying load. The results are applicable for so-called quasibrittle solids.

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
