Abstract: | Multi-domain elastostatic problems can often be efficiently solved using coupled single domain iterative techniques. A particular difficulty however is the decrease in convergence rate associated with the increase in number of solution domains. Further convergence difficulties are encountered for multi-domain problems where contacting domains suffer variable contact conditions. Problems of this type are evident in pressure die casting with die blocks coupled together prior and subsequent to thermal loading. Particular interest in this paper is the development of an efficient solution methodology for prediction of gaps at block interfaces in pressure die casting. |
