Energy Dissipation in Nonlinearly Elastic Auxetic and Non‐Auxetic Mechanical Metamaterials with Friction and Material Damping

open access: yesAdvanced Engineering Materials, EarlyView.
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 ...

Vietnamese Civic Organisations: Supporters of or Obstacles to Further Democratisation? Results from an Empirical Survey

open access: yesJournal of Current Southeast Asian Affairs, 2016
In political science and in development cooperation, civic organisations (COs) under authoritarian rule are usually seen as supporters of processes that move towards democratisation. However, these organisations are sometimes criticised for their support

C and S induces changes in the electronic and geometric structure of Pd(533) and Pd(320)

open access: yes, 2006
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.

Mitigation of Cracks in High‐Performance Nickel‐Based Superalloys in Powder Bed Fusion Laser Beam of Metals Using a Metal Matrix Composite Approach

open access: yesAdvanced Engineering Materials, EarlyView.
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?

open access: yesJournal of Current Southeast Asian Affairs, 2015
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?

On the Deformation Behavior of Metastable CrMnNi Steels Processed by Directed Energy Deposition in Different Temperature Regimes

open access: yesAdvanced Engineering Materials, EarlyView.
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

China’s Potential for Economic Coercion in the South China Sea Disputes: A Comparative Study of the Philippines and Vietnam

open access: yesJournal of Current Southeast Asian Affairs, 2012
With tensions rising in the South China Sea, China’s use of its economic leverage over Southeast Asian countries has recently come into focus. With increasing economic and trade ties between China and Southeast Asia, the question being asked is whether ...

Nonparametric estimation with aggregated data. [PDF]

open access: yes
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

Impact of Hot Isostatic Pressing on Microstructure Evolution and Creep Performance of Powder Bed Fusion–Laser Beam Processed CM247LC

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of Hot Isostatic Pressing (HIP) temperature on the microstructure and creep performance of powder bed fusion–laser beam processed CM247LC superalloy is investigated. Grain growth and γ’ precipitate evolution are characterized following HIP at varying temperatures.
