Thermal structural ratcheting simulation—Evaluation of industrial-used constitutive models

open access: yes, 2023
International audienceThis article presents an evaluation of the performance of conventional constitutive models in modelling the structural ratcheting of an austenitic stainless steel structure subjected to a thermomechanical loading.

Rearrangement Towards Stability: Plastic Shakedown in Granular Materials Under Thermal Cycles

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Granular materials are routinely subjected to thermal cycling due to natural and anthropogenic phenomena. Despite the ubiquity of this occurrence and its relevance for science, engineering, and technology, the long‐term thermo‐mechanical response of granular materials to repeated heating and cooling remains poorly understood.

A new four-dimensional ratcheting boundary : derivation and numerical validation [PDF]

open access: yes, 2018
A new four-dimensional ratcheting boundary is derived analytically for the first time considering the interaction among four types of stresses: constant mechanical membrane stress, mechanical bending stress, cyclic thermal membrane stress, and thermal ...

Effects of adjustable‐volume transfemoral prosthetic sockets on balance and falls: A randomized clinical trial

open access: yesPM&R, EarlyView.
Abstract Background Adjustable‐volume prosthetic sockets have been developed to allow users to accommodate volume fluctuations throughout the day. Improvement in socket fit is thought to enhance the connection between the user's residual limb and prosthesis and may therefore improve postural control and balance.

Molecular Active Matter, Kinetic Asymmetry, and Non‐Reciprocal Interactions

open access: yesSmall, EarlyView.
Nanoscale enzymes constitute dissipative active matter that converts scalar energy input into vectorial outputs. Through kinetic and diffusion asymmetry, they break time and space symmetry, resulting in directional motion. This mechanism accounts for both positive and negative chemotaxis, as well as non‐reciprocal interactions between enzymes that ...

Ratcheting Assessment of Medium Carbon and Austenitic Steel Alloys at Elevated Temperatures

open access: yesJournal of Manufacturing and Materials Processing
The present study intends to evaluate the ratcheting of ER9 wheel medium carbon steel and austenitic steel samples at room and elevated temperatures subjected to uniaxial loading cycles through the use of the Ahmadzadeh–Varvani (A–V) kinematic hardening ...

Bending Ratcheting Tests of Z2CND18.12 Stainless Steel

open access: yes, 2010
A series of ratcheting experiments under bending loading for Z2CND18.12 stainless steel were carried out on a dynamic mechanical analyzer. The characteristic of progressive inelastic deformation of the material in the different temperatures and different

The Feasibility of Household Food Waste Reduction in Finland: Insights From Five Consumer Profiles

open access: yesAustralian 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 ...
