Background

Raghu Pucha obtained his PhD in 1995 from Indian Institute of Science, Bangalore. He held post-doctoral research positions at Nanyang Technological University, Singapore and Purdue University, West Lafayette before coming to Georgia Tech in 2000. His research focuses on developing upfront computational tools for the design, analysis and manufacturing of composite materials. His research contributions in composite materials include (i) Special purpose finite elements for design and delamination failure analysis of fiber reinforced laminated composites (ii) Microstructure simulations for impact damage analysis of composites  (iii) Design, analysis and optimization tools for advanced composites in electronics applications. His current research includes design and analysis of nano-filler composites for structural, electronics and bio applications.  Dr. Pucha teaches computer graphics, CAD/CAE and design courses.

Integrated Analytical and Computational Tools (IntACT) for Composites with Nanofillers

Advanced composite materials with nanofillers are increasingly replacing the metal counterparts in many applications. Manufacturing and application of nanocomposites need upfront computational tools for detail application specific analysis and characterization. Dr. Pucha’s current research efforts are focused on developing integrated analysis and computational tools of manufacturing and application of nanocomposites. These integrated tools systematically consider and quantify many manufacturing parameters in modeling 3D network of nanofillers in a RVE of matrix. The developed continuum models can be used for mechanical and electrical characterization of nanocomposites for various applications. The automated tools with user interface can provide quick what-if analysis and characterization data for manufacturing nanocomposites with application specific properties.
