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.
Asymmetric acoustic energy transport in non-Hermitian metamaterials
One of our studies on linear and nonlinear non-Hermitian metamaterials has been published on the recent special issue of the Journal of the Acoustical Society of America: Non-Reciprocal and Topological Wave Phenomena in Acoustics.

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?

I think the content would be of much interest for the community.
Postdoctoral Research Opportunities at EPUSP
The Fracture Mechanics and Structural Integrity Research Laboratory (NAMEF) of the Polytechnic School of Engineering at the University of São Paulo (EPUSP) has openings for 2-year postdoctoral fellows (which may be extended to an additional year depending on funding availability) with a strong background in fracture mechanics, fatigue and computational modeling of materials starting from August/2019 or September/2019. Interested applicants can see details in the attached document.
