Initial blank design of deep drawn orthotropic materials using inverse finite element method
In this work, an inverse finite element formulation was modified for considering material anisotropy in obtaining blank shape and forming severity of deep drawn orthotropic parts. In this procedure, geometry of final part and thickness of initial blank sheet were known. After applying ideal forming formulations between material points of initial blank and final shape, an equation system was obt...
متن کاملextra high limiting drawing ratio (ldr=9) cylindrical deep drawing based on finite element and experiment
deep drawing of cylindrical shapes with high limiting drawing ratio (ldr) values is relatively difficult. annealing is a further operation, which in turn adds costs and consumes significantly time to the forming process. in the present work, cylindrical cups from brass sheet were made with only limited anneal during few steps, but having ldr of 9 that is about 2 times higher than previous works...

متن کاملfinite element simulation of process and springback of friction aided deep drawing using tapered blank holder divided into eight segments
in this paper, a novel technique on friction aided deep drawing using tapered blank holder divided into eight segments is proposed to overcome defect of friction aided deep drawing using four segments tapered blank holder technique. a taper blank holder is designed to be of two parts: stationary part with 5 degree taper angle and moving parts divided into eight tapered segments. the main functi...
متن کاملMinimization of the Sheet Thinning in Hydraulic Deep Drawing Process Using Response Surface Methodology and Finite Element Method
In most of the sheet forming processes, production of the parts with minimum thickness variation and low required force is important. In this research, minimization of the sheet thinning and forming force in the hydraulic deep drawing process has been studied. Firstly, the process is simulated using the finite element method (FEM) and simulation model is verified using the experimental results....
