Improved specimen recovery in tensile split Hopkinson bar [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 This paper presents an improved specimen recovery method for the tensile split Hopkinson bar (TSHB) technique. The method is based on the trapping of residual stress waves with the use of momentum trap bars. As is well known, successful momentum trapping in TSHB is highly sensitive to experimental uncertainties, especially on the incident bar side of ...

Biotechnology and Bioengineering, EarlyView.ABSTRACT The design of biological carbon capture systems to uptake carbon dioxide by photoautotrophic cultivation of algae has been proposed to mitigate atmospheric carbon emissions. Multiple models to predict algal growth as a function of nutrients have been proposed, but few have delved into the complex dynamic reactions of algal growth as influenced

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 ...

Effects of porosity on dynamic indentation resistance of silica nanofoam. [PDF]
, 2017 The dynamic indentation behaviors of monolithic silica nanofoams of various porosities are investigated. When the pore size is on the nm scale, as the porosity increases, despite the decrease in mass density, the resistance offered by silica nanofoam to ...

Development and Validation of a Hopkinson Bar for Hazardous Materials [PDF]
Experimental Mechanics, 2020 Abstract Background There are a variety of approaches that can be employed for Hopkinson bar compression testing and there is no standard procedure. Objectives A Split-Hopkinson pressure bar (SHPB) testing technique is presented which has been specifically developed for the characterisation of hazardous materials such as radioactive metals.

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 ...

Nickel-titanium pseudo-elastic behavior under equi-biaxial dynamic loading conditions
EPJ Web of Conferences, 2018 Shape memory alloys (SMA) undergo a solid-solid phase transformation called martensitic transformation, involving a "high temperature" phase (austenite) and a "low temperature" phase (martensite).
