Nonthermoelastic martensitic features in ideal martensites due to volume effects

Y Yang, Y Xu, Y Zhou, X Ding, J Sun, T Lookman… - Physical Review B, 2023 - APS
We study martensitic transformation behavior by considering the coupling of volumetric
strain and the transformation strain in a group-subgroup transformation within a Ginzburg …

Maturation of crack patterns

EA Jagla - Physical Review E—Statistical, Nonlinear, and Soft …, 2004 - APS
Superficial (two-dimensional) crack patterns appear when a thin layer of material elastically
attached to a substrate contracts. We study numerically the maturation process undergone …

Doping effects of point defects in shape memory alloys

Y Yang, D Xue, R Yuan, Y Zhou, T Lookman, X Ding… - Acta Materialia, 2019 - Elsevier
Doping point defects into shape memory alloys (SMAs) influences their transformation
behaviors and mechanical properties. We propose a general Landau free energy model to …
