Research Areas

Improving performance limits of novel materials

In order to meet 21st Century challenges, we need to design and manufacture novel materials that are strong, light weight, durable and multifunctional. Despite significant breakthroughs in recent decades, materials fail at 1/10th or less of their intrinsic limits. This failure of materials is the principle bottleneck for developing future energy, healthcare, aerospace and automotive technologies.

In the past, advances in materials science involved extensive laboratory testing coupled with a healthy dose of guesswork. Often, this approach is expensive and time-consuming. Computational Materials Engineering (CME) permits controlled experimentation on computers and assists in designing novel materials. We employ a combination of newly developed CMS techniques to investigate following research problems:

Atomistic modeling of nano-scale fracture and failure

Our lab uses a combination of modern atomistic modeling techniques (Molecular Dynamics, Density Functional Theory) to develop a more fundamental understanding of the deformation and failure mechanisms in a variety of new-age materials such as graphene, nano-composites, nuclear and energy storage materials.

Improving strength and fracture properties of nano-composites used in tissue engineering through atomistic based multiscale modeling

Tissue damage due to congenital diseases, accidents and end-stage organ failures affects millions of people worldwide. Fortunately, it is now possible to engineer tissues in vitro that can specifically meet the needs of individual patients. Carbon nanotubes blended with Chitosan show significant improvement in mechanical properties such as stiffness and hardness. However, their interfacial strength and fracture toughness properties fall below expectations. By investigating failure characteristics, we develop a route for improving structural properties of these novel materials.

Developing efficient energy storage materials

By employing modern electron structure calculation techniques, our team tries to improve energy storage capabilities of nano-structured materials.

Designing ultra-strong alloys by nanostructuring

The strength of alloys comes from a variety of hardening mechanisms such as precipitation hardening, solid-solution hardening, grain boundary hardening etc. Until now, development of these alloys has been empirical in nature. By combining atomistic and continuum simulation approaches, we investigate different strength contributions and develop new alloys that have optimum strength and hardness characteristics.
