Criteria for selecting a reasonable and better measure of anisotropy

Published in Physcal Review Letters: Many materials are anisotropic. However, there is no widely accepted measure for characterizing the degree of elastic anisotropy. Here, assuming that the limiting case of extreme anisotropy should possess a positive semidefinite stiffness matrix, we propose three criteria to evaluate measures of anisotropy and show that the existing measures in the literature do not satisfy all of the proposed criteria.

Dynamics of periodically coupled parallel flexural elements: towards the modular design of metamaterial beams

Periodic systems have attracted a lot of attention in science and engineering due to the existence of band gaps in their frequency spectra. Here, we study the flexural wave propagation in beams that are periodically connected in parallel and investigate how the contrast in the material and cross-sectional properties may affect the band structure of these systems and their dispersion properties.

Multiscale Design of Graphyne‐Based Materials for High‐Performance Separation Membranes Computational modeling and simulations play an integral role in the bottom‐up design and characterization of graph‐n‐yne materials. Here, the state of the art in modeling α‐, β‐, γ‐, δ‐, and 6,6,12‐graphyne nanosheets for synthesizing graph‐2‐yne materials and 3D architectures thereof is discussed.

Paraffin-enabled graphene transfer We report a transfer approach using paraffin as a support layer, whose thermal properties, low chemical reactivity and non-covalent affinity to graphene enable transfer of wrinkle-reduced and clean large-area graphene.

Postdoctoral Research Fellow Position at the University of São Paulo, Brazil.

We are looking for a candidate with a Ph.D. degree to study fracture problems in bimetallic pipelines,  API X65 internally clad with alloy 625. The project has direct application to offshore exploration in Brazil deepwater fields. The project is going to be funded by the Petrobras company. The chosen candidate will develop a parametric model to model the welded joint of this type of pipes using python/Abaqus, being the numerical model as close as possible to the real geometry.

Ph.D. positions on Nucleation-Controlled Plasticity at the Technion

The Nanomechanics Simulations Laboratory at the Technion (Haifa, Israel) is seeking applicants for a computational study on nucleation-controlled plasticity. Immediate openings are available for Ph.D. students in several projects. In these projects, you will develop models for the strength of specimens at the nanoscale, to account for the effect of temperature and lattice defects on the nucleation-controlled strength.
