Understanding the fracture toughness of glasses is of prime importance for

science and technology. We study it here using extensive atomistic simulations in

which the interaction potential, glass transition cooling rate, and loading geometry

are systematically varied, mimicking a broad range of experimentally accessible

properties. Glasses’ non-equilibrium mechanical disorder is quantified through

A_g, the dimensionless prefactor of the universal spectrum of non-phononic

In this project, the research fellow is expected to work on the K&C concrete model in LS-DYNA. Focusing on normal strength concretes of ~45 to 60 MPa compressive strengths, the research fellow has to calibrate the material parameters against experimental data, and to establish all modelling inputs for simulating the response of concrete structures against very high impact loading conditions. The numerical predictions will be benchmarked against experimental data.

The Laboratory for Fluid-Structure Interaction (LIFE) (http://labfsi.com/) of the Department of Mechanical Engineering at the Universitat Rovira i Virgili (URV) (www.urv.cat) in Tarragona (Spain), is looking for an enthusiastic research student with a strong interest in fluid dynamics and fluid-structure interactions. Successful candidates will join a small but very active multidisciplinary team, working in several fluid-structure interaction (FSI) problems.

We developed an inverse design method for constructing 3D reconfigurable architected structures — we synthesized modular origami structures whose unit cells can be volumetrically mapped into a prescribed 3D curvilinear shape followed by volumetric shrinkage for constructing modules. After modification of tubular geometry, we searched modular origamis’ geometry and topology for target mobility using a topological reconstruction of modules.

Traditionally dynamic analysis is done using Newton’s universal laws of the equation of motion. According to the laws of Newtonian mechanics, the x, y, z, space-time coordinate system does not include a term for energy loss, an empirical damping term “C” is used in the dynamic equilibrium equation. Energy loss in any system is governed by the laws of thermodynamics. Unified Mechanics Theory (UMT) unifies the universal laws of motion of Newton and the laws of thermodynamics at ab-initio level.

Our group in the Department of Mechanical and Industrial Engineering at New Jersey Institute of Technology (NJIT) is working on a range of problems, involving mechanics and physics of 2D materials, soft materials and biological systems. We employ methods of continuum mechanics, mathematics, statistical physics and atomistic simulations to explore the mechanics of 2D materials, electromechanical coupling in soft materials, as well as physical mechanisms underlying the interface of nanomaterials and biology.
