Viscoelastic Modeling of Stress Relaxation in Model High‐Performance Covalent Adaptable Networks

Journal of Polymer Science, EarlyView.
Covalent adaptable networks, often referred to as vitrimers, contain a certain fraction of bonds that are able to exchange with other bonds. The ability of this bond exchange to relax stress or result in flow of the material depends on the concentration and specific concentration of these bonds in ways that can be quantified.

Extensional Rheology and Extrusion Blow Molding of Idealized High‐Density Polyethylene/Polypropylene Blends as Model Post‐Consumer Resins

Journal of Polymer Science, EarlyView.
Compatibilization markedly improves the top‐load compression performance and structural integrity of HDPE/PP blow‐molded bottles. Neat HDPE, PP, and HDPE/PP bottles exhibit premature neck cracking at relatively low strains, whereas the compatibilized HDPE/PP/C blend sustains substantially higher loads and greater deformation without cracking ...

Design and Development of a Modular Ballistic Pendulum for High‐Impulse Measurement in Contact and Near‐Field Explosive Loading

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measuring impulse from explosive charges in contact and near‐field configurations presents practical challenges due to wide variation in impulse magnitude. Ballistic pendula are widely used for impulse measurement, but many existing designs are limited to narrow operating envelopes or are poorly suited to repeated contact testing and tamped ...

Vickers Microhardness as a Viable Mechanical Property Measurement Technique for High Explosive Materials

Propellants, Explosives, Pyrotechnics, EarlyView.
There are multiple drivers for the development of reliable mechanical property techniques for high explosive (HE) samples, particularly smaller HE samples. While Vickers microhardness is a commonly used technique for mechanical characterization in metals and other materials, there has been little work using this technique for HE materials, particularly

Portfolio‐Level Reliability Analysis of a Multi‐Asset System: A Frailty Proportional Intensity Modeling Framework

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Understanding and modeling the equipment failure behavior is crucial for reducing downtime, optimizing maintenance strategies, and improving operational safety. This challenge becomes particularly critical in industrial contexts involving multi‐asset portfolios, where heterogeneous conditions influence the reliability of individual assets and,

Application of Circular Economy Principles to Power Generation: Extending the Life of A Hydropower Plant by Pumped Hydro Energy Storage

Sustainable Development, EarlyView.
ABSTRACT The application of circular economy, which aims to maximize efficiency and reduce waste, to renewable energy sources necessitates, given the intermittent nature of the latter, robust energy storage solutions to ensure grid stability and avoid wasting energy.
