Research Interests
Dr Achuthan’s research is in the areas of solid mechanics and advanced materials. Currently, he is focusing on acoustic meta-materials, surface nanocrystallization of metals, and health monitoring of wind turbines.  He is interested in studying and solving problems associated with the development of next generation “small” scale devices such as MEMS and nanodevices. In the advanced materials area Dr Achuthan’s current focus include multiscale modeling of ferroelectric material behavior, Molecular Dynamic simulation of nanomaterial behavior, and developing composite materials for harsh environment conditions. Dr Achuthan is also working on structural impact problems and thermal stress analysis problems for refractory structures.
