| Abstract: | Some local region of the highly pressurized nozzle junction will be in elastoplastic stage. An efficient method has been developed by using the coupling of boundary element to finite element techniques. This is a new way for using combination of BEM with FEM. The cost of computations are substantially reduced in comparison with the conventional FEM throughout the whole region. |
