Low volume-fraction microstructures in martensites and crystal plasticity

We study microstructure formation in two nonconvex singularly-perturbed variational problems from materials science, one modeling austenite-martensite interfaces in shape-memory alloys, the other one slip structures in the plastic deformation of crystals. For both functionals we determine the scaling of the optimal energy in terms of the parameters of the problem, leading to a characterization of the mesoscopic phase diagram. Our results identify the presence of a new phase, which is… Expand

Deformation concentration for martensitic microstructures in the limit of low volume fraction
We consider a singularly-perturbed nonconvex energy functional which arises in the study of microstructures in shape memory alloys. The scaling law for the minimal energy predicts a transition from aExpand
Geometry of martensite needles in shape memory alloys
This work presents a two-dimensional shape optimization model based on finite elasticity and discusses its numerical solution, indicating that the tapering profile of the needles can be understood within infinite elasticity, but not with linearized elasticity. Expand

We consider a singularly-perturbed two-well problem in the context of planar geometrically linear elasticity to model a rectangular martensitic nucleus in an austenitic matrix. We derive the scalingExpand

We consider a partial differential inclusion problem which models stress-free martensitic inclusions in an austenitic matrix, based on the standard geometrically nonlinear elasticity theory. We showExpand

Energy Bounds for a Compressed Elastic Film on a Substrate
The fracture term is included, transforming the elastic minimisation into a free boundary problem, and opening the way for patterns which result from the interplay of elasticity and delamination in a compressed elastic film which delaminates from a substrate. Expand
A branched transport limit of the Ginzburg-Landau functional
We study the Ginzburg-Landau model of type-I superconductors in the regime of small external magnetic fields. We show that, in an appropriate asymptotic regime, flux patterns are described by aExpand

Branching of twins in shape memory alloys revisited

Microstructures in Low-Hysteresis Shape Memory Alloys: Scaling Regimes and Optimal Needle Shapes
For certain martensitic phase transformations, one observes a close relation between the width of the thermal hysteresis and the compatibility of two phases. This observation forms the basis of aExpand
Dislocation Microstructures and the Effective Behavior of Single Crystals
Abstract.We consider single-crystal plasticity in the limiting case of infinite latent hardening, which signifies that the crystal must deform in single slip at all material points. This requirementExpand
Nucleation Barriers for the Cubic-to-Tetragonal Phase Transformation
We are interested in the phase transformation from austenite to martensite. This transformation is typically accompanied by the generation and growth of small inclusions of martensite. We consider aExpand
Branching of twins near an austenite—twinned-martensite interface
Abstract We study the role of surface energy in determining twin width near an austenite—twinned-martensite interface. We find that there are two distinct regimes, depending on the relative values ofExpand
