TL;DR: In this article, the integral equation method was used to obtain the scattered field of a normally incident plane wave from an elliptic crack embedded in an isotropic elastic medium, and it was shown that the determination of the diffracted field depends on the solution of integro-differential equation.

TL;DR: In this paper, a recently developed integral equation method is used to solve the problem of interaction between coplanar, elliptic cracks under normal loading, where the pair of dual integral equations in a Cartesian system is first transformed to four sets of infinite systems of Fredholm integral equations of the second kind in a cylindrical polar coordinate system.

TL;DR: In this paper, an earthquake source is simulated as a simple finite source, and the transient response of the surface displacement of an elastic half space due to the above internal source is calculated, using a series of transformations, followed by the traditional Cagniard-de Hoop technique.

TL;DR: In this paper, the authors considered the effect of the free surface on the stress distribution of an elliptic crack aligned parallel to the free boundary and at a depth h below it.

TL;DR: In this article, the Cagniard De-Hoop technique was used to generate a pulse in an elastic half space by impulsive normal pressure over a circular area on the surface.
