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.

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]. 

Post doctoral position at IIT Kanpur, India

A post doctoral position (funded by Boeing USA) will be available from September 2019 at the Indian Institute of Technology Kanpur, India. The project involves Finite Element studies on the welding of thermoplastics. Candidates need to be have a background in non linear Solid Mechanics with experience of implementing user subroutines in ABAQUS. Familiarity with cohesive zone models will help. Initial appointment will be for a year.

Interested candidates can write directly to me at sbasu@iitk.ac.in.

Flexoelectricity as a universal mechanism for energy harvesting from crumpling of thin sheets

Can the mere crumpling of a paper produce electricity? An inhomogeneous strain can induce electrical response in all dielectrics and not just piezoelectric materials. This phenomenon of flexoelectricity is rather modest unless unusually large strain gradients are present. In this paper, we analyze the crumpling of thin elastic sheets and establish scaling laws for their electromechanical behavior to prove that an extremely strong flexoelectric response is achieved at submicron length scales.

Axisymmetric JKR-type adhesive contact under equibiaxial stretching

 Our research has just been published in Journal of Adhesion. It deals with axisymmetric frictionless adhesive contact problem for a spherical indenter pressed against an isotropic elastic incompressible half-space under equibiaxial stretching is studied in the framework of the generalized Johnson{Kendall{Roberts (JKR) theory, which accounts for the effect of weak coupling between fracture modes I and II by means of a phenomenological mode-mixity function. The model predicts that contact area can withstand a larger level of the substrate stretch under moderate pre-pulling force.
