fracture

Job description: We are seeking innovative and highly motivated PhD candidates to join the FROG lab in the mechanical engineering department at the University of Ottawa.

Dear Colleagues,

Any fracture process ultimately involves the rupture of atomic bonds. Processes at the atomic scale therefore critically influence the toughness and overall fracture behavior of materials. Atomistic simulation methods including large-scale molecular dynamics simulations with classical potentials, density functional theory calculations and advanced concurrent multiscale methods have led to new insights e.g. on the role of bond trapping, dynamic effects, crack-microstructure interactions and chemical aspects on the fracture toughness and crack propagation patterns in metals and ceramics.

Soft materials including elastomers and gels are pervasive in biological systems and technological applications. Whereas it is known that intrinsic fracture energies of soft materials are relatively low, how the intrinsic fracture energy cooperates with mechanical dissipation in process zone to give high fracture toughness of soft materials is not well understood. In addition, it is still challenging to predict fracture energies and crack-tip strain fields of soft tough materials.

A new postdoctoral fellow position is available within the Hopkins Extreme Materials Institute (hemi.jhu.edu) at Johns Hopkins University.  The position is in the area of experiments and modeling of inelastic deformations in geological materials (including damage and micromechanics of fracture) under impact mechanical loading conditions.  The potential candidate will (a) assist in the development of theoretical and computational models for dynamic behavior and failure of geological materials, (b) closely interact with experts in x-ray phase contrast imaging to characterize microcr

Three post-doctoral positions are available at the University of Luxembourg with the ERC RealTCut project.
