SIMULATION AND OPTIMIZATION OF T-SHAPED TUBE HYDROFORMING PROCESS USING ABAQUS/CAE

Abstract

The paper presents a detailed simulation procedure for the tube hydroforming process using Abaqus/CAE software, applied to seamless CDA110 copper tube billets. Through experiments with varying fluid pressure and axial feeding values, the study analyzes the interaction between stress and strain at the T-shaped bulge of the billet. The simulations identified optimal parameters to prevent tearing or wrinkling while evaluating the formability of the tube part. These findings contribute to a valuable reference database for designing and optimizing the tube hydroforming process in mechanical manufacturing.
