The use of weight functions is a well-established technique for the solution of mechanics problems in structural engineering. Increasing use of these techniques is being made to solve crack problems. The special feature of crack problems in elasticity is the presence of a singular stress field at th
## 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
