Postdoctoral Position in computational solid mechanics at Aarhus University, Denmark

Applications are invited for a 2 year postdoctoral position with a background in computational solid mechanics. The focus of the project will be on micromechanics of failure in materials surface with applications in tribology and micro-machining. This research opportunity broadly involves development of physics-based computational approaches and systematic simulations for understanding the process of surface failure under different loading condition (e.g.

Effects of surface tension on the suction forces generated by miniature craters

There are emerging demonstrations that micro- or nano-craters engineered on polymer surfaces can enable enhanced adhesion. In the past, we have developed a framework for quantifying the suction forces produced by isolated macroscopic craters neglecting surface effects. In this paper, we take surface tension into consideration because it plays a significant role in miniature craters on soft polymers. We have derived linear and nonlinear elastic solutions for the elasto-capillary distortion in miniature hemispherical craters whentheyare demoldedfromthe template.

Faculty positions available at METU Northern Cyprus Campus

The Department of Aerospace Engineering at Middle East Technical University (Northern Cyprus Campus) invites applications for faculty positions to begin in 2018. Topics of interest include advanced structures and materials, aeroelasticity, aerodynamics, flight mechanics and control, advanced propulsion systems, and space applications. Outstanding candidates in other synergistic areas will be considered as well. Even though the emphasis is preferably on individuals at the Assistant Professor level, the other ranks will also be considered.

On Weingarten-Volterra defects

Amit Acharya

The kinematic theory of Weingarten-Volterra line defects is revisited, both at small and finite deformations. Existing results are clarified and corrected as needed, and new results are obtained. The primary focus is to understand the relationship between the disclination strength and Burgers vector of deformations containing a Weingarten-Volterra defect corresponding to different cut-surfaces.

How to Realize Volume Conservation During Finite Plastic Deformation

Volume conservation during plastic deformation is the most important feature and should be realized in elastoplastic theories. However, it is found in this paper that an elastoplastic theory is not volume conserved if it improperly sets an arbitrary plastic strain rate tensor to be deviatoric. We discuss how to rigorously realize volume conservation in finite strain regime, especially when the unloading stress free configuration is not adopted in the elastoplastic theories.

Postdoctoral Position At Northwestern University

A postdoctoral associate position is available immediately at the Computational Nanodynamics Laboratory at Northwestern University with Prof. Sinan Keten. This research project focuses broadly on the atomistic and multi-scale modeling of biomolecular materials such as nanocellulose and their interfaces with polymers. A Ph.D. in a related field is required for this position. Expertise in atomistic and molecular modeling techniques (molecular dynamics, density functional theory, coarse-grained molecular simulations) is required. Additionally, a strong background in soft matter research (polymer science, biophysics, or related areas) is highly desired. Interested candidates should send a CV, a summary of research interests, contact information of three references, and three most relevant publications as a single pdf file to s-keten@northwestern.edu. Evaluations will begin immediately, and the start date is flexible.

Postdoctoral and PhD positions in Stochastic Computational Mechanics, Duke University

Several positions at the PhD and postdoctoral levels are available in the group of Prof. Guilleminot at Duke University. The ideal candidates should have a particular interest in conducting interdisciplinary research at the interface of computational mechanics, materials science and uncertainty quantification. Topics of interest include (but are not limited to) stochastic modeling and computational frameworks for large-scale nonlinear materials and systems, statistical inverse problems and multiscale approaches.

IUTAM Symposium on Architectured Materials Mechanics: Call for abstracts

This "Architectured Materials Mechanics" IUTAM (http://iutam.org/) Symposium will take place September 17-19, 2018 in downtown Chicago, Illinois. It aims to provide a state of the art on the engineering science (design, fabrication, mechanics) of architectured materials including (but not limited to): lattice materials, metamaterials, origami, topologically interlocked materials and bioinspired materials. The list of invited speakers can be found on the symposium website:

Mechanical Reading of Ferroelectric Polarization

The mechanical properties of materials are insensitive to space inversion, even when they are crystallographically asymmetric. In practice, this means that turning a piezoelectric crystal upside down or switching the polarization of a ferroelectric should not change its mechanical response. Strain gradients, however, introduce an additional source of asymmetry that has mechanical consequences.
