The problem of two collinear cracks of equal length and normal to the strip boundaries in an infinitely long piezoelectric strip of finite width is analyzed. By using the Fourier series method, the mixed boundary value problem is reduced to triple series equations, which are then transformed to a si

## 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
