A simulation of bending by the rigid-plastic hybrid element method

Author(s): K-M Guo & K. Nakanishi Abstract: In this paper, a bending process is analyzed by using the rigid-plastic hybrid element method (HEM). The rigid-plastic HEM is a mixed approach of the rigidplastic domain-BEM and the rigid-plastic FEM. For the rigid-plastic HEM, the compatibilities of not only velocity but also velocity's derivative between the adjoining boundary elements and finite elements can be met, the velocity and the derivative of the velocity can be calculated with the same precision. While, for the conventional rigid-plastic FEMs, the velocity and the derivative of the velocity cannot be calculated with the same precision. Therefore, it may be considered that the rigid-plastic HEM is a more precise method than the conventional rigid-plastic FEMs. A plane strain bending problem is analyzed by the rigid-plastic HEM. Contours of effective strain rate, effect... Pages: 10 Size: 318 kb Paper DOI: 10.2495/CMEM030051
