โœฆ Synopsis

The problem of opening two coplanar Griffith cracks in an infinite elastic medium has been considered in this note. The application of Somigliana's method to this mixed boundary value problem leads to a F/~ppl integral equation, whose solution has been derived in closed form with the help of a convolution theorem connected with finite Hilbert transforms. 1 y ( x -t) ],~, uy(x,y)= f U ' ( t ) [ l t a n -' ( ~--~) รท 2,r(l_v)(x_t)2+ y2j,-, (2.2) --00

In this paper, the three-dimensional problem of two coplanar Griffith cracks propagating uniformly in an elastic medium has been considered. Equal and opposite tractions which are triaxial in nature are applied to the crack surfaces. The two-dimensional Fourier transforms have been used to reduce th

Ah&met--The problem of determining the transient stress distribution in an infinite elastic medium weakened by two coplanar Griffith cracks is considered. To the surfaces of the cracks, an internal pressure is applied suddenly. The problem is reduced to that of solving dual integral equations in the
