Mesoscale theory of grains and cells: crystal plasticity and coarsening
, 2006 Solids with spatial variations in the crystalline axes naturally evolve into cells or grains separated by sharp walls. Such variations are mathematically described using the Nye dislocation density tensor.

Advanced Engineering Materials, EarlyView.This study investigates the bond quality of co‐extruded aluminum–titanium hybrid profiles, focusing on the lateral angular co‐extrusion (LACE) process. It examines how heat treatments (HT) affect intermetallic phase formation, bond strength, and material properties.

Melting as a String-Mediated Phase Transition
, 2000 We present a theory of the melting of elemental solids as a dislocation-mediated phase transition. We model dislocations near melt as non-interacting closed strings on a lattice.

A Novel Simulation Approach for Damage Evolution during Tailored Forming
Advanced Engineering Materials, EarlyView.Traditional damage models are struggling to accurately and efficiently simulate large‐scale three‐dimensional models with a great number of degrees of freedoms. A new gradient‐enhanced damage model based on the extended Hamilton principle can significantly reduce the computation time while ensuring mesh‐independence which is suitable to use in tailored

Dislocation constriction and cross-slip in Al and Ag: an ab initio study
, 2002 A novel model based on the Peierls framework of dislocations is developed. The new theory can deal with a dislocation spreading at more than one slip planes.
