✦ Synopsis

The present paper extends the method of integral equation developed in Part I "Roy and Chatterjee\ 0883# to the three!dimensional problem of interaction between two equal coplanar elliptical cracks embedded in an in_nite isotropic elastic medium under shear loading[ The dual integral equations obtained from the mixed boundary value problem in the present situation are coupled and reduced to in_nite systems of Fredholm integral equations of the second kind*four systems corresponding to the _rst crack and four to the second crack[ Analytical expressions for the two tangential displacement functions have been given up to the order b 4 "b being the crack separation parameter#[ Numerical results for the two shear stress intensity factors\ K 1 "8# and K 2 "8#\ together with the interaction e}ects have been tabulated and illustrated graphically[

We consider the problem of determining the stress distribution in an infinitely long isotropic homogeneous elastic layer containing two coplanar Grifith cracks which are opened by internal shear stress acting along the lengths of the cracks. The faces of the layer are rigidly fixed. The cracks are l

This paper includes the analysis of the interactions of two coplanar elliptical cracks, with equal or different crack sizes, embedded in finite thickness plates under uniform tension. The ratios of crack depth to crack length (bt/a~ and b,\_/a~.) are 0.25 and 1.0; the relative distances between two

In an earlier paper [6] we have studied the case of interaction of shear waves with a crack centrally situated in an infinite elastic strip; we, in this paper, extend the study to the case of two coplanar Griffith cracks. An integral transform method is used to find the solution of the equation of m
