Dr. Gayan Aravinda Abeygunawardane | Magnetoelectrics | Innovative Research Award
Senior Lecturer at University of Moratuwa | Sri Lanka
Dr. Gayan Aravinda Abeygunawardane is a researcher in mechanics of advanced materials whose work spans computational modelling, material behavior, biomaterials, and applied structural analysis, contributing significantly to both scientific understanding and industrial innovation. His research integrates nonlinear finite element analysis, crystal plasticity, fracture modelling, multiphysics coupling, and materials characterization to address complex challenges in metallic glasses, steels, elastomeric systems, biomedical materials, and semiconductor engineering. His published work includes studies on shear band initiation in bulk metallic glasses, indentation-induced deformation localization, crack propagation in notched specimens, electroplasticity in steels, muscle-tissue biomechanics, thermal and mechanical behavior of tire compounds, heat-transfer enhancement using graphite, and 3D-printed cellulosic composites. He has contributed to computational frameworks for oxygen-diffusion-assisted crack growth, user-defined material subroutines for industry-grade FEA solvers, and predictive simulation tools for polymer and rubber manufacturing. His recent biomedical engineering research explores piezo-magnetostrictive laminates for wireless bone-healing stimulation, external-fixator performance, and hybrid scaffold mechanics. His work is disseminated through Scopus-indexed journals, international symposiums, and collaborative research outputs, totaling 65 citations, 11 documents, and an h-index of 4. His contributions include journal publications in materials science, biomechanics, polymer science, fracture mechanics, and computational modelling, alongside several conference papers and a national patent for a trilayer piezomagnetostrictive bone stimulator. His research demonstrates a consistent innovative trajectory, combining fundamental mechanics with applied engineering solutions across multiple disciplines.
