Journal Club for August 2019: Instabilities in Soft Composites

 instabilities1  

Elastic instability is a fascinating phenomenon playing an important role in pattern formations in soft biological systems. The phenomenon also has been actively used by the (i-)mechanics and physics community to design new (meta-) materials with switchable microstructures, properties, and functions [1].

Universal features in "stickiness" criteria for soft adhesion with rough surfaces

A very interesting recent paper by Dalvi et al. has demonstrated convincingly with adhesion experiments of a soft material with a hard rough material that the simple energy idea of Persson and Tosatti works reasonably well, namely the reduction in apparent work of adhesion is equal to the energy required to achieve conformal contact. We demonstrate here that, in terms of a stickiness criterion, this is extremely close to a criterion we derive from BAM (Bearing Area Model) of Ciavarella, and not very far from that of Violano et al.

Introduction

Post-Doc Position: Computational Fluid Dynamics

We have an opening for a post-doc position at George Mason University starting in the beginning of October. The preferred qualification for the position is a strong background in computational fluid dynamics involving short-duration dynamic loads (e.g. underwater explosion). Expertise in fluid-structure interaction is a plus. Candidates from aerospace, mechanical, civil, and related engineering areas will be considered. Inquiries can be sent directly to Girum Urgessa at gurgessa@gmu.edu with a CV/resume attached.

Jaw Selection for Tensile Testing Grips

Tensile grip jaw selection plays an important role for successful mechanical tests as if specimen slippage between the jaws occurs or if the specimen breaks or tears in the jaw area testing may need to be discarded. This post covers the available jaw surface types for tensile grips and also the operation of quick-change type jaws.

Why are most 2D lattices hexagonal? The stability of 2D lattices predicted by a simple mechanics model

Published in Extreme Mechanics Letters: https://doi.org/10.1016/j.eml.2019.100507. For more than half a century, physicists rejected the existence of two-dimensional (2D) materials since they theoretically underestimated the stability. However, the discovery of one-atom-thick graphene proved the inapplicability of this theory.

Reconstruction of Governing Equations from Vibration Measurements for Geometrically Nonlinear Systems

Data-driven system identification procedures have recently enabled the reconstruction of governing differential equations from vibration signal recordings. In this contribution, the sparse identification of nonlinear dynamics is applied to structural dynamics of a geometrically nonlinear system. First, the methodology is validated against the forced Duffing oscillator to evaluate its robustness against noise and limited data.
