Experimental and finite element simulation of formability and failures in multilayered tubular components

AbstrAct Purpose: Optimization of the operating conditions is one of the most significant studies in the hydroforming process, which affect the forming of successful components. Design/methodology/approach: Finite Element simulations have been carried out using the commercial finite element package ANSYS in order to predict the most efficient and acceptable operating condition for certain material properties of multilayered blank and initial blank geometry. Findings: This paper studies the hydroforming process involving combined (axial feed and internal pressure) and multi stage non-linear loading action theoretically and experimentally for a multi layered tubular blank placed in a pre-shaped die block. Research limitations/implications: Finite Element simulation of a multi layered tube hydroforming and optimisation of the best forming conditions based on a number of simulations were carried out to avoid wrinkling or bursting of the tubular blanks. Originality/value:
