“…According to Li et al [21], the different micro-swinging angles had negligible effect on the interface temperature at the centre of the weld. Bikmeyev et al [22] used a 3D model to investigate the mechanisms behind the formation of the plasticised layer (start of phase 2). The model demonstrated that the plasticised layer initially forms at the centre of the weld, which was confirmed with experiments.…”

Linear friction welding (LFW) is a solid-state joining process that significantly reduces manufacturing costs when fabricating Ti-6Al-4V aircraft components. This article describes the development of a novel 3D LFW process model for joining Ti-6Al-4V. Displacement histories were taken from experiments and used as modelling inputs; herein is the novelty of the approach, which resulted in decreased computational time and memory storage requirements. In general, the models captured the experimental weld phenomena and showed that the thermomechanically affected zone and interface temperature are reduced when the workpieces are oscillated along the shorter of the two interface contact dimensions. Moreover, the models showed that unbonded regions occur at the corners of the weld interface, which are eliminated by increasing the burn-off. ARTICLE HISTORY

Linear friction welding (LFW) is a solid-state joining process used to weld non-axisymmetric components. Material joining is obtained through the reciprocating motion of two specimens undergoing an axial force. During this process, the heat source is determined by the frictional work transformed into heat. This results in a local softening of the material and plays a key role in the onset of the bonding conditions. In this paper, a critical analysis of the different approaches used to simulate the LFW processes is provided. The focus of the paper is the comparison of different modeling strategies and the most relevant outputs available, i.e. temperature, strain and stress distribution, material flow, axial shortening and residual stress. Major issues arising due to the complexity of the process are discussed, highlighting strengths and weaknesses of each approach
