Abstract

Regularization procedures for damage problems P. Broi Department of Engineering Structures, Klokner Institute of the Czech Technical University, Prague, Czech Republic Abstract In this paper, a boundary element method for a category of nonlocal damage simulations is presented. The formulation and also the boundary element calculation code put together in the course of this investigation have turned out to be very simple and effective, yielding trustworthy data about the strains and stresses in damage-softening models. In the numerical interpretation, a finite-grid is applied to assess the damage magnitudes, including an example by the way of an illustration. 1 Introduction Damage is the progressive physical procedure by which materials break. The damage mechanics is the investigation, via mechanical variables, of the systems included in this deterioration when the materials are subject to loading. At the microscale plateau this is the microstress accumulation in the vicinity of defects or i
