Optimization of Bursting Behavior of AA2090 Al-Alloy Pipes Using Taguchi Techniques and Finite Element Analysis

R. Venkata Sai Krishna Varma, A. Chennakesava Reddy

Abstract: The optimization of bursting behavior of liquid and gas pipe lines is very important with respect to safety. In this paper 3D finite element analysis and Taguchi technique were employed to investigate fracture criteria of AA2090 Al-alloy pipes subjected to internal bursting pressure. The ultimate tensile strength criterion was employed to study the failure of pipes. The heat treatment was the major dominating control factor effecting the bursting of pipes.

Keywords: AA2090 Al-alloy, bursting pressure, crack length, crack depth, heat treatment, finite element analysis.
