Size-dependent transformation patterns in NiTi tubes under tension and bending: Stereo digital image correlation experiments and modeling
Aslan Ahadi, Elham Sarvari, Jan Frenzel +3
The dependence of transformation pattern in superelastic NiTi tubes on tube outer diameter D and wall-thickness t is investigated through quasi-static uniaxial tension and large-ro…
A note on thermomechanical coupling effects in the indentation of pseudoelastic shape memory alloys
Mohsen Rezaee-Hajidehi, Mahdi Neghabi, Stanislaw Stupkiewicz
While macroscopic experiments on polycrystalline shape memory alloys (SMAs) reveal significant thermomechanical coupling effects arising from the latent heat of transformation, the…
Twin branching in shape memory alloys: a 1D model with energy dissipation effects
Stanislaw Stupkiewicz, Seyedshoja Amini, Mohsen Rezaee-Hajidehi
We develop a 1D model of twin branching in shape memory alloys. The free energy of the branched microstructure comprises the interfacial and elastic strain energy contributions, bo…
Energy and morphology of martensite-twinned martensite interface in CuAlNi shape memory alloy: a phase-field study
Seyedshoja Amini, Mohsen Rezaee-Hajidehi, Stanislaw Stupkiewicz
Needle-like twins are observed experimentally within the transition layer at the martensite-twinned martensite interface. We utilize a phase-field approach to investigate this micr…
