000015323 520__ $$2eng$$aThe axial buckling of pseudoelastic NiTi tubes is studied through a combination of experiment and analysis. On reaching the martensite transformation stress the tube buckles first into an axisymmetric mode and subsequently locally collapses developing a non- axisymmetric mode with three circumferential waves. Under displacement control, collapse leads to progressive development of additional mode-3 lobes. On unloading, the material transforms back to austenite, deformation is recovered, and the buckling lobes are erased. A finite element model coupled with a custom constitutive model is used to successfillly simulate the experiment. The constitutive model uses kinematic hardening to simulate the stress nonlinearity associated with the reversible phase transformation, and incorporates the tension/compression asymmetry exhibited by the material used.
