Degradation and Failure Analysis of Environmental Barrier Coatings under Adverse Operating Environment: Multi-Physics Modelling
… methodologies. Thermal cycle-induced temperature fields were implemented into the EBC model, aiming to simulate the system's in-service conditions. Coupled thermo-mechanical processes were simulated, incorporating high-temperature creep behavior, phase transformation from Yb₂Si₂O₇ to Yb₂SiO₅, and …

Phase field modeling of the defect evolution and failure
… work.</p> <p>In the first part of the work, a phase field dislocation dynamics (PFDD) approach is introduced, which tracks the evolution of the dislocations in ultrafine and nano grained metals and takes into account the elastic interaction between dislocations, obstacles and the applied …

Continuum modeling of electro-chemo-mechanical phenomena in all-solid-state batteries
… electrolyte (SSE) due to metal deposition, interphase formation at the anode/SSE interface and damage of the various phases in composite electrodes. Computational modeling for SSBs is at its infancy and constitutes the focus of this thesis, with an emphasis on mechanical integrity of composite …

Physics and Chemistry Based Constitutive Framework for Thermo-Chemo-Mechanical Responses of Polymeric Materials
… of this work has been to identify the relevant damage processes affecting the lifetime of polymeric materials, and to develop predictive physics- and chemistry-based, thermodynamically consistent constitutive frameworks to evaluate their response under extreme environmental condition. A series …
