Non-affine fields in solid-solid transformations: the structure and stability of a product droplet
Arya Paul, Surajit Sengupta, Madan Rao
We describe the microstructure, shape and dynamics of growth of a droplet of martensite nucleating in a parent austenite during a solid-solid transformation, using a Landau theory…

Plasticity and reversibility of structural transitions in a model solid
Arya Paul, Surajit Sengupta, Madan Rao
We formulate a phenomenological elasto-plastic theory to describe a solid undergoing a structural transition from a square (p4mm) to an oblique (p2) lattice in two dimensions. With…

Elastoplastic model for the dynamics of solid-solid transformations : role of non-affine deformation in microstructure selection
Jayee Bhattacharya, Arya Paul, Surajit Sengupta +1
We study the nucleation dynamics of a model solid state transformation and the criterion for microstructure selection using a molecular dynamics (MD) simulation. Our simulations sh…
