탄소성 정적해석시 해에 미치는 여러인자들의 비교연구

A series of parametric study was performed for the investigation of the influence of several analysis parameters to the solution behavior in the elasti-plastic-static analysis of sheet metal forming. The parameters taken into the consideration in the present study are finite element mesh distribution and numerical integration scheme, The elstic-plastic-static analysis was performed for two cases : deflection by a point force bending by a punch Results obtained with different selections of the parameters were compared with each other experimental measurements and analytical solutions.
