Computational analysis of linear friction welding process and micromechanical modeling of deformation behavior for medium carbon steel

Abstract

Finite element simulation of linear friction welding (LFW) medium carbon steel was carried out using the ABAQUS software. A two-dimensional (2D) coupled thermo-mechanical model was established. First, the temperature fields of medium carbon steel during LFW process were investigated. And then, the Mises stress and the 1st, 2nd and 3rd principal stresses fields’ evolution of the steel during LFW process were studied. The deformation behavior of LFW carbon steel was analyzed by using micromechanics model based on ABAQUS with Python code. The Lode parameter was expressed using the Mohr stress circle and it was investigated in detail.
