Three-dimensional elastic compatibility and varieties of twins in martensites
KØ Rasmussen, T Lookman, A Saxena, AR Bishop… - Physical Review Letters, 2001 - APS
We model a cubic-to-tetragonal martensitic transition by a Ginzburg-Landau free energy in
the symmetric strain tensor. We show in three dimensions (3D) that solving the St. Venant …

Power-law statistics for avalanches in a martensitic transformation
R Ahluwalia, G Ananthakrishna - Physical Review Letters, 2001 - APS
We devise a two-dimensional model that mimics the recently observed power-law
distributions for the amplitudes and durations of the acoustic emission signals observed …

Time evolution of tetragonal-orthorhombic ferroelastics
SH Curnoe, AE Jacobs - Physical Review B, 2001 - APS
We study numerically the time evolution of two-dimensional (2D) domain patterns in proper
tetragonal-orthorhombic (TO) ferroelastics. Our equations of motion are derived from …

Instability of Alexander-McTague crystals and its implication for nucleation
W Klein - Physical Review E, 2001 - APS
We show that the argument of Alexander and McTague, that the bcc crystalline structure is
favored in those crystallization processes where the first-order character is not too …
