Computational Mechanics Laboratory

Karan S. Surana, Director

The Computational Mechanics Laboratory (CML) is the focal point of computational mechanics research and development in linear and non-linear solid mechanics, structural mechanics and composite mechanics, fluid dynamics (newtonian, generalized newtonian and viscoelastic fluids), error estimation, h-, p-adaptive methods for smooth and singular problems, special element formulations (l elements) for singular problems, numerical simulation of moving fronts such as: elastic and inelastic wave propagation in isotropic, orthotropic and composite materials, acoustic waves, low speed and high speed compressible flows, reacting flows and fluid-structure interaction.

Various research and development activities in the Laboratory foster new methodologies, innovative algorithms for computational formulations and techniques primarily focused in the Finite element area.

The nature of the laboratory, breath of various diverse research activities, expertise of the individuals involved, availability of up-to-date computing facilities and many software tools provide an attractive, conducive and efficient environment for research and development in various areas of computational mechanics.
