Influence of Temperature on Scratch and Wear Properties of Technical Thermoplastics: Implications for Material Selection

Advanced Engineering Materials, EarlyView.
The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Effect of Thermomechanical Processing on the Impact Deformation of Additively Manufactured 316L Stainless Steel

Advanced Engineering Materials, EarlyView.
Previous studies on additive manufacturing primarily focus on the mechanical properties of as‐printed components. In the present work, researchers explore the potential of employing novel thermomechanical postprocessing techniques to improve the microstructure after printing.

Scalable Fabrication of Height‐Variable Microstructures with a Revised Wetting Model

Advanced Engineering Materials, EarlyView.
Height‐variable microstructures are fabricated using a scalable CO2 laser machining approach, enabling precise control of wettability through structural gradients. Classical wetting models fail to capture height‐induced effects, necessitating a revised theoretical framework.

The condition for dynamic stability.

Journal of Biomechanics, 2005
The well-known condition for standing stability in static situations is that the vertical projection of the centre of mass (CoM) should be within the base of support (BoS). On the basis of a simple inverted pendulum model, an extension of this rule is proposed for dynamical situations: the position of (the vertical projection of) the CoM plus its ...

Dynamic Stability of Copper Single-Atom Catalysts under Working Conditions.

Journal of the American Chemical Society, 2022
The long-term stability of single-atom catalysts is a major factor affecting their large-scale commercial application. How to evaluate the dynamic stability of single-atom catalysts under working conditions is still lacking.

Dynamic Stability Analysis and Improved LVRT Schemes of DFIG-Based Wind Turbines During a Symmetrical Fault in a Weak Grid

IEEE transactions on power electronics, 2020
With the increasing penetration of the wind power, the stability issues of the weak AC grid-connected doubly fed induction generator (DFIG)-based wind turbines during low-voltage ride through (LVRT) cannot be neglected.

Dynamic Stability

The Oxford Handbook of Danish PoliticsThe Oxford Handbook of Danish Politics, 2020
Danish voter behaviour has been characterized by increasing volatility, suggesting a growing pool of floating voters. This interpretation, however, does not seem fitting.
