This study presents a hyperelastic mechanical metamaterial for elastic energy dissipation. Energy is dissipated within its unit cells by friction assisted by material damping. Frictional contact is enhanced when using auxetic unit cells. The load–displacement plot for one compression cycle shows a pronounced hysteresis loop, indicating that a large ...

‘Get Back’ Graphic Works by Pete Clarke [PDF]
Pete Clarke is an artist who explores representations of the changing city as a political metaphor for concepts of modernity and history. He aims to create a significant aesthetic practice by exploring and challenging the definitions, assumptions and ...

C and S induces changes in the electronic and geometric structure of Pd(533) and Pd(320)
We have performed ab initio electronic structure calculations of C and S adsorption on two vicinal surfaces of Pd with different terrace geometry and width.

High‐performance nickel‐based superalloys are often not processible in additive manufacturing (AM) due to hot cracking. The findings in this manuscript propose an efficient method to mitigate cracking and enhance mechanical properties of these alloys by producing a metal matrix composite, contributing to the material and process perspective of the AM ...

The European Union’s Myanmar Policy: Focused or Directionless?
What is the European Union (EU) trying to achieve in Myanmar? Is the EU speaking with one voice and acting collectively (and does it really matter)? Were the sanctions lifted too early?

In the present study, metastable CrMnNi steels with varying chemical compositions and a concomitantly altered stacking fault energy are processed via directed energy deposition and afterwards tested via tensile tests at different temperatures. The present study shows the influence of the manufacturing process on the elemental deformation mechanisms for

Nonparametric estimation with aggregated data. [PDF]
We introduce a kernel-based estimator of the density function and regression function for data that have been grouped into family totals. We allow for a common intrafamily component but require that observations from different families be independent. We
