Abstract

The paper addresses the issue of how material micro-structure relates to fracture-toughness, the focus being on brittle disordered materials. The problem is investigated numerically through lattice discretization simulations of the rupture process. The spatial variation of dissipated energy due to fracture is evaluated, and under certain conditions, it is found that its distribution is characterized by a multifractal spectrum. The multifractal spectrum, f(α), depends not only on the initial disorder present in the material, but also on the nature of the externally applied load. It is found that when the disorder of the material increases, the relative total dissipated energy decreases, and vise versa.
