We develop a singular crack element for the general anisotropic solids in two dimensions for the mixed mode boundary element analysis of multiple straight cracks. Given a normalized crack along an interval (−1, +1) on the X-axis, we represent the crack opening displacement (COD) by the continuous distribution of dislocation dipoles, which is interpolated by the Chebyshev polynomials with the p1 − X2 weight function. The analytical integration of the dislocation dipole distribution leads to adoi:10.14713/ejbe.v1i3.766 fatcat:3ch6znjgwrh6pgfcanurrk2ada
