• A combined method of the usual energy method with the rigid plastic finite element method (FEM) is proposed. In this method a velocity field is expressed by a linear combination of a number of simple velocity fields and the unknown coefficients of that expression are determined by minimizing the total energy dissipation. Improved points are as follows : (i) difficulty in introducing a suitable velocity field in the usual energy method is reduced to a great extent, (ii) computation time is shortened by applying a technique in FEM and limitation of degree of freedom in the velocity field in the energy method is removed, and (iii) main part of program of computation is made common to general plastic workings. This method is applied to the analysis of flat-rolling of a bar, and it is found that rolling properties and deformation agree well with experimental ones.
