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.

Magneto-elastic composite

Dear all,

May I bring your attention to recent papers of our that deals with fibre-reinforced magneto elastic composite at large strain?

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.

How to integrate with 6 tying points (TP) for transverse shear and 4 TP for in-plane shear, in case of Assumed Natural Strain?

Hi Experts,

I am presently working with a 9-node shell element and understood that there were many rigid body modes available even with reduced integration.

Thus, I am planning to implement Assumed Natural Strain and found out that there will be 6 integration points for transverse shear strains gamma_xz and gamma_yz and  nominal strain while there are only 4 typing points in-plane shear strain.

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.
