... instabilities. Design/methodology/approach In this work, FE simulation of end forming of raw tubes and FSPed AA6063-T6 tubes are done using Abaqus (explicit) incorporating anisotropic properties of the raw tube and FSPed zone. Actual thickness of the FSPed zone is also implemented. Expansion, reduction...

Introduction Stability analysis and yarn deformation modelling and simulation are important topics in engineering design, computer graphics and more generally in the textile industry. In fact, the mechanical behaviour...
