The sheet material slab is subjected to the displacement at the top of the punch. In slab method of analysis it is assumed that plane sections before the deformation remain plane during deformation. Slab method of analysis has been used for solving metal forming problems for a long time. The accuracy of the traditional slab method, a well established method to calculate forming forces for simple metal forming operations, is investigated for the upset forging of a cylindrical billet. Analysis and modeling play a vital role for accessing the feasibility of sheet metal forming processes. 2. مشخصات نویسندگان مقاله A generalized 3-D slab method of analysis for metal forming problems K Abrinia - Mechanical Engineering Department College of Engineering, University … However it has been restricted to plane strain and axisymmetric problems due to limitations in its formulations. In this paper a new formulation has been proposed so that it could be applied to three dimensional problems in metal forming. The analytical values by the slab … Process simulations thus help reduce cost and lead time and allow for exploring new process designs without building expensive equipment. The model is a forming case in which the die and punch are made up of steel. Building A Large Post Frame Garage Full Time-lapse Construction: NEVER BEFORE SEEN FOOTAGE - Duration: 16:28. 5 show the comparisons of compression force among the slab method analysis, the FEM simulation, and the experiment, considering whether the rotation is considered or not. Metal forming processes, also known as mechanical working processes, are primary shaping processes in which a mass of metal or alloy is subjected to mechanical forces. This tutorial demonstrates a nonlinear static analysis of metal forming simulation using nonlinear material and contact. Nevertheless, the method is highly useful because it gives simple closed form solutions which are reasonably reliable. By mechanical working processes, the given shape and size of a machine part can be achieved with great economy in material and time. It can provide useful data for the die design and production design in metal forming process. The non-uniformity in metal flow as described above is not taken into account. Fig. The conditions are ω = 0, ω = 0.16 rad/s, and μ = 0.214. Under the action of such forces, the shape and size of metal piece undergo a change. Nowadays, almost no tool design in industrial stamping is manufactured without successful virtual tryout. 4, Fig. The goal of this analysis is to introduce you to the elasto-plastic nonlinear material.
