Computational modelling of blanking processes - remeshing and transfer issues

Onderzoeksoutput: Hoofdstuk in Boek/Rapport/CongresprocedureConferentiebijdrageAcademicpeer review

Samenvatting

Finite element simulations of blanking require frequent remeshing in order to trace the evolving geometry of the problem. Remeshing must be accompanied by transfer of a set of state variables from the old mesh to the new. Inaccuracies which are inevitably introduced by this transfer may easily lead to loss of convergence in subsequent loading increments and therefore to breakdown of the simulation. In order to avoid such failures, a remeshing-transfer algorithm has been developed which is more forgiving with respect to inaccuracies and thus allows for efficient and robust simulations.
