Design of Numerical Simulations of Linear Friction Welding Processes: Issues and Difficulties

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

In this paper, a critical analysis of the technical difficulties and numerical issues inrunning simulations of linear friction welding processes is carried out. The focus of the paper is thecomparison of different modeling strategies of a numerical analysis for the LFW process of Ti-6Al-4V titanium alloy, for which the thermal aspect strongly influences the mechanical behavior due tothe phase transformation, taking place over a definite range of temperature. A 3D simulationcampaign, conducted using the FEA code DEFORM™, was considered in order to showadvantages and disadvantages of each approach, including the most critic limitations andcomplexity in a correct simulation design using two deformable objects
