Optimization of Fracture Behavior of AA6061 Al-Alloy Pipes Using Finite Element Analysis
D.U.M. Manikanta, A. Chennakesava Reddy
Abstract: In this paper 3D finite element analysis and Taguchi technique were employed to investigate fracture criteria of 6061 Al-alloy pipes subjected to internal bursting pressure. The ultimate tensile strength and yield strength criteria were used to study the failure of pipes. It was observed that the J-integral was proportional to the deformation under the applied bursting pressure. It was noticed that the major dominating control factors which could influence the failure of pipes were the pipe thickness, depth of crack and the bursting pressure.
