Unilateral crack identification: a filter-driven, iterative, boundary element approachUnilateral crack identification: a filter-driven, iterative, boundary element approach Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-112000enAn identification problem for parametric variational inequalities and linear com-plementarity problems is solved here by means of iterative filter techniques. A concrete application in engineering mechanics, the unilateral crack identification problem, is solved. The elastic contact problem is formulated by boundary element-linear complementarity techniques. By means of numerical results and comparison with previous approaches based on optimization and neural networks it is shown that this method is advantageous. In view of the difficulty of the considered bilevel optimization problem, this approach may be of interest for other applications as well.http://creativecommons.org/licenses/by/4.0/Journal of Global Optimization1-417339-352 Stavroulakis Georgios Σταυρουλακης Γεωργιος H.
