On the visualization of joint formation during linear friction welding

Abstract

A 3D computer model of the preliminary and the transition phases of LFW using ANSYS was developed. Based on the adhesion phenomena theory, we introduce a simple method to evaluate the areas of joint formation. Results of this evaluation are in good agreement with experiments. Custom software for the 3D-simulation of the process of joint formation and material movement into the flash was built, which used the results of the FEM model.
