A modified split hopkinson torsional bar in studying shear localization
, 1995 A modified split Hopkinson torsional bar (SHTB) is introduced to eliminate the effect of the loading reverberation of the standard SHTB on the study of evolution of shear localization.

On backward dispersion correction of Hopkinson pressure bar signals [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 Elastic theory shows that wide spectrum signals in the Hopkinson pressure bar suffer two forms of distortion as they propagate from the loaded bar face. These must be accounted for if accurate determination of the impact load is to be possible. The first form of distortion is the well-known phase velocity dispersion effect.

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 ...

Influence of Strain Rate and Temperature on the Visco-Plastic Properties of Commercially Pure Titanium and Ti6Al4V Titanium Alloy [PDF]
Problemy Mechatroniki, 2015 The paper presents results of tests concerning visco-plastic properties of commercially pure titanium and Ti6Al4V titanium alloy. The analyses were carried out at wide range of strain rates from 2 x 10[sup]-4[/sup] s[sup]-1[/sup] to 2 x 10[sup]3[/sup] s ...

EPJ Web of Conferences, 2012 When designing a split Hopkinson system, the yield strength of the selected pressure bar material determines the maximum stress attainable within deforming samples and also, the maximum striker velocity that is usable to prevent plasticity in bars.

High Strain-Rate Material Model Validation for Laser Peening Simulation
The Journal of Engineering, 2015 Finite element modeling can be a powerful tool for predicting residual stresses induced by laser peening; however the sign and magnitude of the stress predictions depend strongly on how the material model captures the high strain rate response.
