Uniaxial deformation of tungsten nanopillars/nanowires/nanotubes: Atomistic and coarse-grained atomistic simulations

Dear Colleague,

In the last two years, we published six papers on uniaxial deformation of tungsten nanopillars/nanowires/nanotubes using atomistic and coarse-grained atomistic simulations:

Abaqus left eigenvalue and eigenvector

Dear all,

 

I am working on the subject of the instability problem using Abaqus. 

One of the representative examples may be the squeal noise. 

 

In the Abaqus simulation, we have the difficulty in obtaining the left eigenvectors. 

 

It seems that the following comments do not work properly to obtain the left eigenvectors. 

 

Does anyone know how to obtain the left eigenvectors in SIM?

Snap-back induced hysteresis in an elastic mechanical metamaterial under tension

We combine experiment and finite element simulation and come up with a design of a mechanical metamaterial which demonstrates snap-back induced hysteresis and energy dissipation. The resultant is an elastic system that can be used reversibly for many times. The underlying mechanism of existence of hysteresis and the physics of snap-back induced elastic instability is unveiled. Our results open an avenue for design and implementation of recoverable energy dissipation devices by harnessing mechanical instability.

Citation metrics author database for many scientific fields

Citation metrics are widely used and misused.  Ioannidis and co-authors have created a publicly available database of 100,000 top scientists that provides standardized information on citations, h-index, coauthorship-adjusted hm-index, citations to papers in different authorship positions, and a composite indicator.

Compatible-Strain Mixed Finite Element Methods for 3D Compressible and Incompressible Nonlinear Elasticity

A new family of mixed finite element methods --- compatible-strain mixed finite element methods (CSFEMs) --- are introduced for three-dimensional compressible and incompressible nonlinear elasticity. A Hu-Washizu-type functional is extremized in order to obtain a mixed formulation for nonlinear elasticity. The independent fields of the mixed formulations are the displacement, the displacement gradient, and the first Piola-Kirchhoff stress. A pressure-like field is also introduced in the case of incompressible elasticity.

How inhomogeneous zipping increases the force output of Peano-HASEL actuators

Please take a look at our newest paper in Extreme Mechanics letters. In this paper we investigate why Peano-HASEL (Hydraulically Amplified Self-healing Electostatic) actuators zip inhomogeneously at large loads. We develop a theoretical model to explain the phenomenon and validate it experimentally. We show that inhomogeneous zipping increases the blocking force of Peano-HASEL actuators by ~50% compared to homgenous zipping. Even though our analysis is limited to Peano-HASEL actuators, the physical principle is valid for other geometries of HASEL acutators, too.
