Mechanics of Materials
Research work in Mechanics of Materials is highly interdisciplinary and centres on the development of novel structural and functional materials for a wide range of technological applications. We establish complex structure-property relationships using state-of-the-art materials characterization techniques, atomic force microscopy, electron microscopy, and estimate mechanical behavior of nanomaterials using MM/MD simulations. Our research spans from buckling of nanotubes, large deformation in single-layered graphene sheets, vibration mode localization in single- and multi-layered graphene sheets to processing and characterizations of advanced materials such as polymers, carbon-carbon/silicon composites, nanocomposites, multifunctional and functionally graded composites.
