Experimental study of the torsional effect for yarn break load test of polymeric multifilaments
Acta Polytechnica, 2022 Polymeric multifilaments have gained a significant interest in recent decades. In the studies of mechanical characteristics, although there are different types of tests, such as rupture, abrasion, creep, impact and fatigue, it can be said that the main ...

Post-impact mechanical characterization of HMPE yarns
Acta Polytechnica, 2021 The present work evaluates the mechanical behaviour of High Modulus Polyethylene (HMPE) yarns after being impacted by sudden axial loads. The influence of loading conditions on the structural integrity of yarns is assessed by tensile, fatigue, and creep ...

Split sleeve cold expansion of AZ31B sheet: Microstructure, texture and residual stress
Materials & Design, 2020 Despite magnesium limited formability at room temperature, split sleeve hole cold expansion of AZ31B sheet was successfully implemented. Microstructural analysis showed greater hardness in the immediate vicinity of the notch, which was due to high ...

Dreaddit: A Reddit Dataset for Stress Analysis in Social Media [PDF]
Conference on Empirical Methods in Natural Language Processing, 2019 Stress is a nigh-universal human experience, particularly in the online world. While stress can be a motivator, too much stress is associated with many negative health outcomes, making its identification useful across a range of domains.
