Abstract
•Fracture locus of a thin-walled tube under axial force and internal pressure is probed.•Fracture parameters are determined by a hybrid experimental-numerical approach.•The Yld2000-2D and Yl2004-3D yield criteria are adopted in a compound solid-shell finite element model.•Proportional loading paths are used to determine the fracture locus.•Non-proportional loading paths are used to establish the path dependence of the fracture locus.
