โœฆ Synopsis

The steady-state vibration of an infinite plate with collinear cracks is considered for low frequency cyclic loading. The formulation of the mixed boundary value problem leads to a dual trigonometric series. The Schwinger's method gives an automatic perturbation scheme. The dynamic stress intensity factor is found to be higher than the corresponding static one. The inertial effect on the stress intensity factor becomes significant only when the frequency of the external load is close to that of the shear wave.

The interaction of time-harmonic elastic waves with a surface-breaking crack, which is inclined under an arbitrary angle with the free boundary of an elastic half-plane, is investigated. Particular attention is devoted to the near-tip stress intensities induced by the incidence of elastic waves. By

A three-dimensional solution is presented for the transient response of an infinite plate which contains a rectangular crack. The Laplace and Fourier transforms are used to reduce the problem to a pair of dual integral equations. These equations are solved with the series expansion method. The stres
