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,

Electromagnetic Compressive Split Hopkinson Bar
, 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. The proposed technology enables to characterize the behaviour of materials under high strain-rates with a small acceleration

A New Specimen Geometry for Compression Hopkinson Bars [PDF]
Le Journal de Physique IV, 1997 This work is concerned with experimental characterization of materials with compression Hopkinson bars. First we point out the importance of friction, elastic punching and parasitic bending on the results of static compression tests with standard cylindrical specimens.

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 ...
