In this paper, dynamic region-wise variational principles have been developed and proved by extending regionwise potential energy principles. Furthermore, we have . gotten dynamic region-wise generalized variation principles by the method developed by prof. Chien Weizang, introducing Lagrangian multipliers and distinguishing them (1980, 1985). Cartesion notations are used in the paper. |
