Veera Sundararaghavan | Faculty

Short Bio

Prof. Sundararaghavan develops multi-scale computational methods for polycrystalline alloys, fiber reinforced composites, metallic foams and ultra-high temperature ceramics to model the effect of microstructure on the overall deformation, fatigue, failure, thermal transport and oxidation response. Recent packages developed include a fully parallel multiscale deformation simulator for optimization of microstructure-sensitive properties in polycrystalline alloys and a new finite element homogenization approach for modeling oxidative degradation in high temperature fiber reinforced ceramic matrix composites. He has made seminal contributions towards the use of multiscale models for accelerated "microstructure-sensitive design" including development of data mining methods for microstructures and reduced order techniques for graphical visualization of microstructure-process-property relationships.
