Title: ONE-STEP INVERSE APPROACH BASED ON QUASI-CONJUGATE-GRADIENT METHOD
Abstract: For the one-step inverse method, an iteration method based on a quasi-conjugate-gradient method is proposed to replace the Newton–Raphson method. It commences from the physical meaning of elemental unbalance force. It does not need to solve the system of finite element equations. It not only inherits the advantage of conjugate gradient method but also avoids non-convergence of the solving process. Finally, the validity of the algorithm proposed is proved by comparing the simulation results obtained by the method in this paper with those obtained through the module of one-step inverse method in Dynaform and practical drawn parts.
