Introduced the idea of multi-scale hyperelasticity as a mechanism for size-dependent plasticity in nano-scale hcp metals. This has relevance to a number of light-weight (Mg, Ti) alloys used in a automobile and aerospace technologies.
Demonstrating how soft phonon modes are responsible for the observed mechanical failure in SiC to be used in power electronic devices.
Analyzed interfacial strength of nano-precipitates in Ni-Al superalloys used in making of blades of jet engines.
