Electromagnetic Compressive Split Hopkinson Bar [PDF]
, 2008 This paper proposes a new design for the compressive split Hopkinson bar that makes use of the intense pressure created in a transient magnetic field formed by the passage of a pulse of electric current through a series of coils.

One-dimensional dynamic compressive behavior of dry calcareous sand at high strain rates
Journal of Rock Mechanics and Geotechnical Engineering, 2019 Calcareous sand has distinct characteristics in comparison with silica sand, such as dynamic behavior at high strain rates (HSRs). This is closely related to pile driving, aircraft wheel loading and mining activities.

Tensions of Sustainability Logics: Performance of a Company Utilizing a Sustainable Business Model
Business Strategy and the Environment, EarlyView.ABSTRACT In recent years, companies have used sustainable business models to gain a competitive advantage. However, there are tensions due to the inconsistency between social, environmental, and economic logic in sustainable business models, making it difficult for companies to change. To understand the existing tensions and interactions between logics,

Business Strategy and the Environment, EarlyView.ABSTRACT Industrial clusters are central to the circular economy transition, yet how they develop into eco‐clusters and the paradoxical tensions this transformation fuels remain underexplored. Drawing on 48 in‐depth interviews and secondary data from a Turkish textile‐recycling cluster, we develop an empirically grounded model of eco‐cluster transition

Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures
Deep Underground Science and Engineering, EarlyView.This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...
