Abstract

Damage models are known to describe the accumulation of continuum damage, the initiation of micro cracks, and their coalescence to macro cracks. The increase of damage generally leads to a local softening behaviour. A local approach to such phenomena may lead to a physically unacceptable localisation of the deformation which gives a spurious mesh sensitivity of the numerical computation. The nonlocal integral type theory overcomes such deficiency. Only a few papers have been published applying the BEM to the nonlocal plasticity and damage. Following a recent paper, the author means to present some BEM results in continuum damage mechanics.
