Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.

Small, EarlyView.ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

True stress-controlled ratcheting behavior of 304LN stainless steel
, 2012 Cyclic plastic deformation response of materials under asymmetric stress cycling is known as ratcheting. Combined effect of fatigue and permanent tensile strain accumulation results in early failure of materials during ratcheting.

The Feasibility of Household Food Waste Reduction in Finland: Insights From Five Consumer Profiles
Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT We apply a household production framework to analyse how changes in cooking skills, waste‐abatement costs and wage rates influence the food waste behaviour of five consumer profiles in Finland. We find that achieving a given reduction in food waste through skill‐enhancing interventions induces larger behavioural adjustments than equivalent ...

Crack growth based life prediction approach under LCF-HCF interaction
Fracture and Structural Integrity, 2019 Prediction of cyclic life under low cycle fatigue - high cycle fatigue (LCF-HCF) interaction is of paramount importance in the context of structural integrity of components in the primary side of fast reactors where such damage under LCF-HCF interaction ...

Australian Journal of Public Administration, EarlyView.Abstract Remarkably little is known about what factors drive success or failure in foreign policy. In part, this is because there is little fundamental agreement on what constitutes success or failure in this domain in the first place. This article engages with these shortcomings by comparing two similar regional order‐building initiatives overseen by ...

Ratcheting and tumbling motion of Vibrots
New Journal of Physics, 2016 Systems of granular rotors (Vibrots), that is, small devices that convert linear vibrational motion into rotation by frictional impact, are of scientific interest since they could reveal various types of collective behavior. Looking at an isolated Vibrot,
