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