InternalK-conversion coefficients of transitions in182W
TheK-conversion coefficients of seven low energy transitions (∼100–400 keV) in182W following the decay of182Ta have been determined by the NPG method using the newly reported γ-ray intensities measured by Ge(Li) detectors.
Abstract 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.
