| Abstract: | This paper focuses on the problem of the evaluation of strains around the inclusions of various shapes and properties located in the uniform matrix undergoing large plastic deformations. The analysis is performed using the rigid-plastic finite-element approach. The uniform plane-strain deformation field is simulated by an introduction of zero friction forces into the program for the compression process. An assumption that the die is wider than the sample allows to simulate ideally uniform flow of metal. Several shapes of the inclusions are investigated, but the results for three most common shapes of the particle's cross-section are presented in the paper. They are: square with the sides parallel to the main directions, square with the sides inclined under an angle of 45° to the main directions and round. |
