4 Steps to Quickly Simulate Your Forging Process with Simulation Software orgers are in a situation today that they must be right, the first time. That too with the least amount of time and money. This means a simulation software to check your metal forming process is inevitable. And what if the forging simulation software…

Effect of friction laws on metal forming simulations – A summary – [2/2] In the previous article, effect of two friction formulations on three processes namely cylinder compression process with low aspect and contact ratio, cylinder compression process with high aspect and contact ratio and the hot strip rolling process were presented. In case you…

Effect of friction laws on metal forming simulations – A summary – [1/2] The series of two articles, to be published in the coming weeks will be based on the effect offrictionformulation on the prediction of metal forming processes. In this article, effect of two friction formulations on three processes namely cylinder compression process with…

Bauschinger Effect in High-Strength Low-Strain-Hardening Materials – Post [1/2] In a series of 2 posts starting this week, the Bauschinger effect in high strength low-strain-hardening materials will be discussed. 1. Introduction It is noteworthy that cold-forged, high-strength materials or parts can often bypass heat treatment after being formed, which minimizes the amount of post-work due…

Effect of flow stress on finite element predictions of metal flow lines in forging In the previous article, it was mentioned that the relatively small dead metal region due to flow stress model employed may cause the difference, which gives us an idea with expectation that a lower limit of flow stress model, i.e., initial…

Effect of friction, temperature and velocity on finite element predictions of metal flow lines in forging In metal forming, especially in forging, metal flow lines formed during rolling or drawing play decisive role at product strength and integrity [1-4]. Of course, they vary globally with plastic deformation due to metal forming. Therefore, they store the…

Finite element analysis of a tube swaging process Swaging process is a metal forming process for manufacturing various mechanical parts by changing cross-sections of rods, tubes and wires [1-10]. There are several advantages of the swaging. First, it is advantageous in mass producing straight or tapered metal shapes with various cross-sections including circle, square, gear…

Comparison of rigid-plastic and elasto-plastic finite element predictions of a tensile test of cylindrical specimens – Post 2  In this continuing post, the results of elastoplastic finite element analysis of the tensile test will be presented. The flow stress shown in Fig. 1, obtained by a material identification algorithm based on rigid-plastic finite element method,…

Comparison of rigid-plastic and elasto-plastic finite element predictions of a tensile test of cylindrical specimens – Post 1  Tensile test gives valuable information about finite element analysis and some criterion on its evaluation. It should be noted that tensile test can be not only used for acquisition of flow stress but it can be also…

Metal forming simulation with emphasis on metal flow lines using AFDEX software  There are so many kinds of failures occurring in developing metal forming processes, which are very costly and time-consuming. Under-filling or overlapping defects can be easily removed using the forging simulation software technologies. In many real situations, in fact, those defects can be…

Finite element analysis model of rotary forging for assembling wheel hubbearing assembly – Post 2/2  This post is in continuation with last week’s post on the finite element analysis model of rotary forging process of a wheel hub bearing assembly. Adding on to that introductory post, the details of the analysis model and the predictions…

Finite element analysis model of rotary forging for assemblingwheel hub bearing assembly – Post 1 This topic will be covered under a series of posts starting from this week. In the past the wheel hub bearing assembly was assembled by incredible methods which were much dependent on the manual experience. Thus, the tolerance changed from…
