A study on plastic strain accumulation caused by traveling of temperature distribution synchronizing with temperature rise

Mechanical Engineering Journal, 2016
The prevention of excessive deformation by thermal ratcheting is important in the design of high-temperature components of fast breeder reactors (FBR). This includes evaluation methods for a new type of thermal ratcheting caused by an axial traveling of ...

Climate Driven Water Table Changes and Their Influence on Liquefaction Response of Integral Bridges

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Integral abutment bridges (IABs) eliminate bearings and joints but transfer seismic demand directly into the surrounding soil, making their response highly sensitive to groundwater conditions and soil–structure interaction. This study presents a 60 g centrifuge testing programme on single‐span IABs designed to isolate the influence of water ...

Use of ultrasonography in assessing peri‐implant osseous defects: An in vitro study

Journal of Periodontology, EarlyView.
Abstract Background The purpose of this study is to investigate the feasibility and diagnostic accuracy of ultrasonography in peri‐implant defect identification and evaluation, and to compare ultrasonography (USG) with cone‐beam computed tomography (CBCT) in defect identification and evaluation in an in vitro model.

Harmonic ratcheting for fast acceleration

Physical Review Special Topics. Accelerators and Beams, 2014
A major challenge in the design of rf cavities for the acceleration of medium-energy charged ions is the need to rapidly sweep the radio frequency over a large range.

Extension of subloading surface model for accurate prediction of elastoplastic deformation behavior of metals with cyclic softening

Nihon Kikai Gakkai ronbunshu, 2014
The subloading surface model has been formulated and applied to the prediction of cyclic loading behavior of metals. However, the existing formulation of this model is limited to metals exhibiting only the cyclic hardening.

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.

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

PM&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.

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 ...

Electrochemical investigation of radical‐radical recognition in viologen‐based ditopic structures

Responsive Materials, EarlyView.
The so‐called “blue box” is one of the most studied macrocycles. Yet, functionalized macrocycles of this type are rarely investigated. This work describes the radical‐radical recognition properties of ditopic structures, including functionalized blue‐box macrocycles.
