The Sound and Vibrations Lab (http://svl.eng.buffalo.edu), directed by Prof. Mostafa Nouh at the University at Buffalo – SUNY, has an opening for a postdoc position in the areas of phononics and elastic metamaterials. The position is supported by an NSF project whose main objective is to investigate the mechanics of space-time-periodic material systems operating within asymmetric, nonreciprocal, non-Hermitian, and/or frequency-selective regimes.

dear collegues, I may be interested to share your views on an "asperity theory" modified Persson's rubber friction contact mechanics theory which I find not clearly motivated and seems to lead to erroneous conclusions ---- but I am also unable to reproduce the results claimed by the authors. The preprint is here, and the original paper attached: https://www.researchgate.net/publication/359392510

Dear colleagues,

A Multiresolution Adaptive Wavelet Method for Nonlinear Partial Differential Equations

If you are interested in the full lecture on the Multiresolution Adaptive Wavelet Method, I have given The Journal of Computational Physics lecture as the part of the Cassyni project.  

Thanks to Weingarten’s formulae [1], which date to 1861, the bending deformation of a Kirchhoff-Love shell can be characterized by examining the variation of the unit normal vector to the surface of the shell. 

Universal displacements are those displacements that can be maintained, in the absence of body forces, by applying only boundary tractions  for any material in a given class of materials. Therefore, equilibrium equations must be satisfied for arbitrary elastic moduli for a given anisotropy class. These conditions can be expressed as a set of partial differential equations for the displacement field that we call universality constraints.

A PhD student position in the field of mechanics is available in the Department of Mechanical and Product Design Engineering at the Swinburne University of Technology (Melbourne, Australia). The project will focus on developing a new energy-absorbing metamaterial, incorporating the synergistic effect of shear-thickening fluid (STF) and cellular structures, for improved mechanical performance under different loading conditions.

Prior experience with finite element methods and impact testings is highly preferred.

This work deals with the small oscillations of two circular cylinders immersed in a viscous stagnant fluid. A new theoretical approach based on an Helmholtz expansion and a bipolar coordinate system is presented to estimate the fluid forces acting on the two bodies. We show that these forces are linear combinations of the cylinder accelerations and velocities, through viscous fluid added coefficients. To assess the validity of this theory, we consider the case of two equal size cylinders, one of them being stationary while the other one is forced sinusoidally.

1. Introduction

The motion of filament-like structures in fluid media has been a topic of interest since long. In this regard, a well known slender body theory exists wherein the fluid flow is assumed to be Stokesian while the filament is modeled as a Kirchhoff rod which can bend and twist but remains inextensible and unshearable. In this work, we relax the inextensibility and unshearability constraints on filaments, i.e., the filament is modeled as a special Cosserat rod.
