In this paper, we present a new convergence rate for both symmetric and nonsymmetric positive definite problems. In our theory, “regularity and approximation” assumption is used. A new rate of convergence estimate with ...

In this paper, quasi-Tresca yield surfaces are reviewed. In order to do elasto-plastic analysis, a new yield criterion is presented. The proposed yield surface can be used in nonlinear three-dimensional analysis of structures. ...

, curved structural components in aerospace industry, etc. In recent years, the rapid development of computer technology enables numerical simulation of sheet metal forming operations by finite element analysis code to be used in an industrial environment...

to produce high-performance coated tools for machining process improvement. Machining tests and finite element analysis were performed to evaluate the proposed novel coating technique. The results obtained from the experiments and simulations demonstrate...
