Significant Research Contribution

His research endeavor concerns the high rate of deformation of materials like alumina, AlN-SiC, Al6061, SS304L, SS316LN, PMMA, GFRP, PC, Biomaterials etc. and their microstructural correlations at various strain rates. There is evidence that in many cases the mechanical properties are significantly dependent on high strain rates.
