The paper presents some aspects regarding the sheet metal deep drawing process and shape optimzation for such parts using Finite Element Analysis. Simulation based design approaches have been used for forming processes. Using similar approach, a full process simulation and optimisation was undertaken in the present work. The work done here involved computer simulations of the forming processes to evaluate the amount of strain and stress each forming process contributed to the final product. Based on the simulation results, recommendation to change the product shape were presented. Not all the virtual products should be manufactured and the Finite Element Analysis eliminate all the possible errors and let the designers to optimize the geometry before designing the Molds and Dies for Deep Drawing process.

This paper “SIMULATION OF THE EFFECT OF DIE RADIUS ON DRAWING PROCESS” is one of the most used Metal Forming Process within the industrial field. Different analytical, numerical, empirical and experimental methods have been developed in order to analyze it. This work reports on the initial stages of finite element analysis (FEA) of a Deep drawing process. The objective of this study is to determine the factors influencing a drawing process and analyzing the process by varying the Die radius and keeping the Friction, Punch radius and Blank Thickness as constant. In this paper Punches, blank thickness of same geometry and dies of various geometries were drawn by using CATIA software. And an effort is made to study the simulation effect of main process variant namely die radius using finite element analysis. As the FEM code, the commercially available software DEFORM-3D is used here. Aluminium alloy 6061 is used for deep drawing with initial diameter as 56mm.

This study intended to establish finite element analysis (FEA) model of warm hydro mechanical deep drawing process (WHMD) of cylindrical cups by means of commercial FEA package Ls-Dyna The validity of established FEA model is verified by means of WHMD experiments through several studies. It was noted that the established model successfully simulated the real process leading to significant cost and time spent on trial-error stage in hydromechanical deep-drawing of lightweight alloys.

Deep Drawing Process

The anisotropic nature of laminated composites creates a unique opportunity and also a great challenge for tailoring their behavior during the forming processes according to the design requirements. In this work, design and simulation of a deep drawing process for fiber-reinforced laminated composites were conducted by using finite element analysis. The effects of the fiber orientation and stacking order on the deep drawing process were investigated based on the basic understanding of forming process of the isotropic aluminum alloy (Al-1100) and laminated composite material (Grilon RVZ-15H nylon/glass). A three dimensional finite element model incorporating layered structural laminates with various fiber orientations was developed. The load-stroke relationship, changes in thickness, and stress-strain distribution were investigated and compared for both aluminum alloy and laminated composites of [0]12, [0/90]6 and [0/90/45/135]3, which can be employed for detailed design and process optimization.
