Variationally Consistent Framework for Finite-Strain Microelasticity
Tushar Jogi
Modeling microstructural evolution at large strains requires mechanical formulations that remain thermodynamically consistent while capturing significant lattice rotations and tran…
Dislocation cartography: Representations and unsupervised classification of dislocation networks with unique fingerprints
Benjamin Udofia, Tushar Jogi, Markus Stricker
Detecting structure in data is the first step to arrive at meaningful representations for systems. This is particularly challenging for dislocation networks evolving as a consequen…
Splitting Instability in Superalloys: A Phase-Field Study
Tushar Jogi, Saurav Shenoy, R. Sankarasubramanian +2
Precipitation-strengthened alloys, such as Ni-base, Co-base and Fe-base superalloys, show the development of dendrite-like precipitates in the solid state during aging at near-$γ^{…
Formation of solid-state dendrites under the influence of coherency stresses: A diffuse interface approach
Bhalchandra Bhadak, Tushar Jogi, Saswata Bhattacharya +1
In this paper, we have formulated a phase-field model based on the grand-potential functional for the simulation of precipitate growth in the presence of coherency stresses. In par…
Stability, Evolution and Switching of Ferroelectric Domain Structures in Lead-free BaZrTiO-BaCaTiO System: Thermodynamic Analysis and Phase-field Simulations
Soumya Bandyopadhyay, Tushar Jogi, Ranjith Ramadurai +1
Enhanced room-temperature electromechanical coupling in the lead-free ferroelectric system BaZrTiO - BaCaTiO (abbreviated as B…
Evolution of interfacial dislocation network during low-stress high temperature creep of particle strengthened alloy system using discrete dislocation dynamics simulations
Tushar Jogi, Saswata Bhattacharya
We use three-dimensional discrete dislocation dynamics simulations (DDD) to study the evolution of interfacial dislocation network (IDN) in particle-strengthened alloy systems subj…
