## a b s t r a c t The problem of two equal-length collinear cracks in an infinite sheet is treated using the weight function method. Exact weight functions for the inner and outer crack tips are derived based on the crack opening displacement solution for a reference load case. These weight functi

β¦ Synopsis
Following Williams [1] and Erdogan [2], Keer and Yahsi investigated the stress distribution at the interface of two infinite strips bonded in a finite region and gave many numerical results [3,4,5]. Here we present an analytical solution (not only at the interface, but also in the whole field) for the same problem (Fig. 1). Our work also partly meets the needs of the artificial crack theory of the recently developed crack technique [6,7,8].

An integral transform method is used to obtain stress distributions in cracked symmetric two-dimensional projections extending out of the half plane. The case considered includes two collinear external Griffith cracks located at the root of the projection. Two loaded cases are considered. Numerical
