Original abstract

There is investigated a crack problem for an array of collinear cracks in composite matrix with their tips allowing to terminate at inclusions interfaces. Inclusions are situated in between the neighbouring cracks tips and exhibit different elastic properties than matrix. The problem is solved using the technique of distributed dislocations and the Bueckner principle. First an approximate fundamental solution for a single dislocation lying in a general point between inclusions centres is developed. The Muschelishvili complex potentials and the Galerkin method for a numerical evaluation of coefficients of suitable chosen base functions are employed.Next the solution for a single dislocation is employed in the distribution of continuously distributed dislocation to cracks modellin
