A plane-strain upper bound limit load solution for bi-material welded joints subject tension is found. It is assumed that each material obeys Hill's orthotropic yield criterion and one of the principal axes of orthotropy coincides with the tensile direction. A crack of arbitrary length is located at

We wish to thank Professor Atkins for his interest and discussion of our paper. Several of the points made in his discussion are most interesting and lead us to add the following observations.
The authors are to be congratulated on an extremely interesting paper in which they unravel some of the mysteries of the biaxial Griffith cracking geometry and report experiments which support the theory that, depending on the value of Poisson's ratio, the critical fracture stress may be increased o
The model of a propagating crack introduced by Craggs for an isotropic solid is extended to the case of general elastic anisotropy. The general theory for propagation under tensile or shear stresses is derived. As for most two dimensional problems in animtropic elasticity, the solution involves the
