Evaluation of Structural Integrity under Bursting Conditions of Heat Treated 2219 Al-Alloy Pipes Using Finite Element Analysis

The structural integrity of liquid and gas pipe lines is very important with respect safety. In this paper 3D finite element analysis and Taguchi technique were employed to investigate fracture criteria of AA2219 Al-alloy pipes subjected to internal bursting pressure. The ultimate tensile strength criterion was employed to study the failure of pipes. The pipe thickness, crack length and heat treatment were the major dominating control factors affecting the bursting of pipes
