Abstract

For many mechanical engineering problems the precise and reliable approxi- mation of stress peaks and gradients is very important, especially in fracture mechanics and generally in continuum damage mechanics. These problems can be regarded as problems of resolution in elasticity. The authors de- termined through previous research^, that the problem can be solved in a very effective way by a decomposition strategy using both the boundary and the finite element methods. The most serious problem in this strategy is the control of the properties of the coupling operators. If the local (BE-) problem is solved by the Neumann series instead of the collocation method, one has the chance to control the solution iteratively in depen
