We derive underdamped evolution equations for the order-parameter (OP) strains of a
proper ferroelastic material undergoing a structural transition, using Lagrangian variations …

Abstract A lattice (or 'grillage') of elastic Rayleigh rods (possessing a distributed mass
density, together with rotational inertia) organized in a parallelepiped geometry can be …

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 …

We study domain patterns in cubic-tetragonal ferroelastics by solving numerically equations
of motion derived from a Landau model of the phase transition, including dissipative …

We study hierarchical structures such as branched twins in elastic materials based on a
model of martensitic materials in which hierarchical twinning near the habit plane (austenite …

A method of introducing an athermal resistance to interface propagation for the Ginzburg-
Landau (GL) approach to the first-order phase transformations (PTs) is developed. It consists …

Nonlinear elasticity in proper ferroelastics is investigated using the Landau theory of phase
transitions. In proper ferroelastics, where certain combinations of strain components es …

Microstructural changes during mechanical shear of a ferroelastic or martensitic material
and their signature in acoustic emission (AE) spectroscopy during strain-induced yield and …

Crystal lattice deformations can be described microscopically by explicitly accounting for the
position of atoms or macroscopically by continuum elasticity. In this work, we report on the …

A thermodynamically consistent framework for combining nonlinear elastoplasticity and
multivariant phase-field theory is formulated at large strains. In accordance with the Clausius …
