Kurzfassung in Englisch

The preprint delivers an efficient solution technique
for the numerical simulation of crack propagation
of 2D linear elastic formulations based on
finite elements together with the conjugate gradient
method in order to solve the corresponding linear
equation systems. The developed iterative numerical
approach using hierarchical preconditioners
comprehends the interesting feature that the
hierarchical data structure will not be destroyed
during crack propagation. Thus, one gets the
possibility to simulate crack advance in a very
effective numerical manner including adaptive mesh
refinement and mesh coarsening. Test examples are
presented to illustrate the efficiency of the
given approach. Numerical simulations of crack
propagation are compared with experimental data.
