A constant-force bistable micromechanism
, 2014 A constant-force bistable micromechanism (CFBM) allowing force regulation and overload protection is developed. When an unknown force is suddenly applied to a microdevice equipped with a CFBM and the unknown force exceeds a critical force of the CFBM ...

Inelastic deformation micromechanism and modified fragmentation model for silicon carbide under dynamic compression [PDF]
, 2018 The underlying micromechanism remains to be clarified for the bulk inelastic behaviour of specific ceramics under impact loads. In this study, the silicon carbide materials were subjected to the split-Hopkinson pressure bar compression in which the ...

Effects of microstructure and crystallography on crack path and intrinsic resistance to shear-mode fatigue crack growth [PDF]
Fracture and Structural Integrity, 2015 The paper focuses on the effective resistance and the near-threshold growth mechanisms in the ferritic-pearlitic and the pure pearlitic steel. The influence of microstructure on the shear-mode fatigue crack growth is divided here into two factors: the ...

Leading the Loop: Anchor‐Led Orchestration in Nascent Circular Ecosystems—A Qualitative Case Study
Business Strategy and the Environment, EarlyView.ABSTRACT The transition towards a circular economy necessitates coordinated, systemic change across value chains. Yet the role of anchor firms in initiating and orchestrating nascent circular ecosystems remains underexplored. Using an inductive, qualitative single‐case design, we analyse a German mid‐sized entrepreneurial firm, drawing on 21 interviews

steel research international, EarlyView.This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...
