Journal Club for October 2019: A Metamaterial Approach to Soft Robotics

Submitted by K. Bertoldi on Thu, 10/03/2019 - 02:12

research

Metamaterials are rapidly emerging at the frontier of science and engineering. Mechanical metamaterials, in particular, have been designed to show superior mechanical properties, such as ultrahigh stiffness and strength-to-weight ratio, or unusual properties, such as a negative Poisson’s ratio and a negative coefficient of thermal expansion.

Wrinkling and smoothing of a soft shell

Submitted by Fan Xu on Thu, 10/03/2019 - 01:11

Transverse wrinkles usually occur in a uniaxially tensile elastic membrane and will be smoothed upon excess stretching. This instability-restabilization response (isola-center bifurcation) can originate from the nonlinear competition between stretching energy and bending energy. Here, we find a crucial factor, the curvature, which can control effectively and precisely the wrinkling and smoothing regimes. When the sheet is bent, the regime of wrinkling amplitude versus membrane elongation is narrowed, with local wrinkling instability coupled with global bending.

Ph.D. positions in Mechanical Engineering at University of Connecticut (UCONN)

Submitted by Osama R. Bilal on Tue, 10/01/2019 - 21:24

job

The lab of Wave Engineering for eXtreme and Intelligent matTEr (We-Xite) has multiple openings for Ph.D. positions. We are looking for exceptional and highly motivated candidates with background in Engineering, Physics, Materials or Mathematics. The research will have a balance between experimental characterizations (non-destructive evaluation of samples fabricated using additive and subtractive methods), numerical simulations (finite element modeling and topology optimization) and analytical derivations (nonlinear dynamics of spring-mass systems).

Effects of solidification defects on nanoscale mechanical properties of rapid directionally solidified Al-Cu Alloy: A large scale molecular dynamics study

Rapid Solidification; Defects; Molecular Dynamics

Directional solidification of Al-11 at % Cu is investigated by molecular dynamics (MD) simulations utilizing second nearest neighbor modified embedded atom method (2NN-MEAM) interatomic potential. The condition for directional solidification is produced by imposing dissimilar temperatures at the model boundaries along the [1 0 0] solidification direction to create a temperature gradient. During solidification, the solid-liquid front travels through the Al-Cu liquid along the [1 0 0] direction towards the high temperature end.
