The remarkable mechanical properties of crumpled materials
Mechanics of crumpled materials
Crumpled materials exhibit unusual and as yet unexpained mechanical properties. Through the surprisingly complex morphologies of facets and ridges formed in the crumpling of paper into a ball or densser materials, very high strength to weight ratios can emerge.
Postdoc Opening in Computational Materials Science at Rutgers University
The microMechanics of Deformation Research Group (mMOD) in the Department of Materials Science and Engineering at Rutgers University is seeking a Post-Doctoral Associate to participate in a pair of collaborative projects with a Department of Energy National Laboratory. The projects are focused on using discrete dislocation dynamics (DDD) simulations to understand dislocation patterning in deformed metals, and molecular dynamics (MD) simulations to understanding crack initiation in hydrogen-affected steels.

The effects of pore geometry on fracture mechanics is studied by considering notches of various types with a uniform crack growth. This work, published in Engineering Fracture mechanics, sheds light on the role of stress concentrators in the toughness of porous materials.
Modelling the influence of strain fields around precipitates on defect equilibria and kinetics under irradiation in ODS steels: A multi scale approach
Resistance to radiation damage is a crucial property for structural materials in fission or fusion reactors. The particle-matrix interface in oxide dispersion strengthened (ODS) steels is considered a sink for point defects created during irradiation. In this work we address the question, if elastic strain fields around oxide particles cause a long-range interaction between the precipitates and point defects. We use kinetic Monte Carlo simulations to simulate the diffusion of point defects under the influence of elastic strain fields caused by Y2O3 and Y2Ti2O7 precipitates.
Post-doc position in microstructure modeling at Nanyang Technological University (NTU) Singapore
The Additive Microstructure Engineering Laboratory (AddME Lab) in the school of Mechanical and Aerospace Engineering at NTU (Singapore) is a young, diverse, and interdisciplinary research group with interests in in-line microstructure control and assessment during selective laser melting (SLM) processes. In this framework, we are collaborating with the Institute of High Performance Computing under the Agency for Science, Technology and Research (A*STAR), to simulate the microstructure of metals produced during SLM.
