“…Ttotal = T0 + Tf where T 0 is the initial ambient temperature and T f is the temperature change caused by the friction heat of the contact interface. The governing equation of the transient heat conduction process is shown in formula (2) [22]: pc∂T∂tfalse(x,y,z,tfalse) = k2▽Tfalse(x,y,z,tfalse) + Qfalse(x,y,z,tfalse) where Q is the friction heat generation rate and Q(x, y, z, t) = ημσ(x, y, z, t) v(x, y, z, t) . Among which η is the heat conversion efficiency, μ is the friction coefficient, σ(x, y, z, t) is the contact stress at coordinates (x, y, z) at time t , and v(x, y, z, t) is the relative slip rate at coordinates (x, y, z) at time t. When heat is generated, the boundary conditions of the friction interface between polymers can be formulated as (3): −k∂T∂n|s = hfalse(Ts − T0false) where T s is the temperature of the friction surface and h is the heat transfer coefficient.…”

Ultrasonic Plasticization Injection Molding (UPIM) is an effective way to manufacture polymeric micro parts and has great potential for energy saving with processing polymeric materials of a small amount. To better control the UPIM process and improve the quality of micro parts, it is necessary to study the heat generation mechanism. In this paper, the interfacial friction heating process of UPIM was studied by finite element (FEM) simulation and experiment, and the temperature change in the friction interface was estimated. Then, the effects of different process parameters such as ultrasonic frequency and ultrasonic amplitude on the friction heating process were analyzed. The results showed that the rising trend of friction heating temperature was transient (finished within 1 s), and the change trend of FEM simulation was consistent with experimental results. Adjusting ultrasonic frequency and amplitude has a significant influence on the friction heating process. Increasing the ultrasonic frequency and amplitude can improve the efficiency of friction heating.

Welding distortion is an unavoidable issue due to localized expansion and contraction during the heating and cooling cycles, and has a negative effect on the fabrication process. However, mitigating weld distortion to meet product requirements is a challenging task, because welding shrinkage can't be prevented, only controlled. This paper provides a comprehensive literature review of various techniques to reduce and optimize the deformation induced by welding in the design stage and manufacturing process. Finite element numerical analysis methods are usually employed to predict welding distortion, and can cost less than actual experiments. The review of these approaches is useful to fully understand the main mechanisms used to mitigate weldinginduced distortion, and for choosing the most suitable method to minimize deformation based on realistic fabrication requirements.
