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 ...

Wave Dispersion and Attenuation in Viscoelastic Split Hopkinson Pressure Bar
Shock and Vibration, 1998 A viscoelastic split Hopkinson pressure bar intended for testing soft materials with low acoustic impedance is studied. Using one-dimensional linear viscoelastic wave propagation theory, the basic equations have been established for the determination of ...

Business Strategy and the Environment, EarlyView.ABSTRACT The transition to a circular economy (CE) remains hindered by the lack of practical strategies that simultaneously secure competitiveness and deliver sustainability outcomes for manufacturing organisations. While circular design is often cited as a cornerstone of CE, its concrete role in driving competitive advantage and organisational ...

Removal of terrestrial DOC in aquatic ecosystems of a temperate river network [PDF]
, 2015 Surface waters play a potentially important role in the global carbon balance. Dissolved organic carbon (DOC) fluxes are a major transfer of terrestrial carbon to river systems, and the fate of DOC in aquatic systems is poorly constrained.

Translating Circularity Into Strategy: A Governance Meta‐Capability Framework
Business Strategy and the Environment, EarlyView.ABSTRACT Firms struggle to transition to circular economy (CE) models, often citing external barriers. Yet some firms succeed, whereas others fail: Why? We argue that success depends on a specific governance capability—a meta‐capability that allows firms to (1) sense and strategically reframe CE imperatives, (2) seize opportunities by aligning diverse ...

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.
