Ratchet limits for a crack in a welded pipe subjected to a cyclic temperature load an a constant mechanical load [PDF]

, 2011
This paper presents the ratchet limit analysis of a pipe with a symmetric crack in a mismatched weld by using the extended Linear Matching Method (LMM). Two loading conditions are considered: i) a cyclic temperature load and a constant internal pressure;

Experimental study on deformation behaviors of saturated soft clay under intermittent cyclic loading with various drained conditions

Yantu gongcheng xuebao
In the previous studies, the cyclic triaxial tests under intermittent cyclic loading are used to study the deformation characteristics of soft clay under traffic loads. Both confining pressure and deviator stress vary cyclically in the stress field under

Coupling effects of cyclic confining pressure and loading frequency on deformation behavior of saturated soft clay under intermittent cyclic loading

Yantu gongcheng xuebao
After the train passes away, the subgrade soils undergo cyclic loading and intermittent periods. The existence of the intermittent period can also affect the mechanical properties of soil.

A multivariate forensic framework for HDPE geomembrane weld failure assessment using stage-based degradation and weld-specific vulnerability indicators [PDF]

E3S Web of Conferences
This paper presents a forensic framework for assessing high-density polyethylene (HDPE) geomembrane weld failures where the weld zone, rather than the parent sheet, governs containment risk.

Effects of intermittently applied cyclic loading on proteoglycan metabolism and swelling behaviour of articular cartilage explants

Osteoarthritis and Cartilage, 1999
The aim of this study was to evaluate the effect of tissue load, frequency and load duration on the biosynthesis and release of proteoglycans (PGs) as well as on the swelling behaviour of cultured mature bovine articular cartilage superimposed with intermittent loads.Cyclic compressive pressure was introduced for 1, 3 or 6 days using a sinusoidal ...

Ofatumumab in Myelin Oligodendrocyte Glycoprotein Antibody–Associated Disease: A Comparison With Rituximab

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate the efficacy and safety of ofatumumab in patients with myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), and compare it with rituximab. Methods We conducted a single–center, observational study including 22 MOGAD patients treated with ofatumumab and 21 treated with rituximab.

Effect of circular holes on the ratchet limit and crack tip plastic strain range in a centre cracked plate [PDF]

, 2011
In this paper a centre cracked plate subjected to cyclic tensile loading and cyclic bending moment is considered. The effect of circular holes drilled in the region of the crack tip on the ratchet limit and crack tip plastic strain range is studied ...

White Matter Hyperintensity Burden and Short‐Interval Change Associated With Sleep Apnoea in the UK Biobank

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Purpose White matter hyperintensities (WMH) are a core neuroimaging marker of cerebral small vessel disease (CSVD). Sleep apnoea (SA) is a recognized vascular risk factor, but its associations with regional WMH burden, short‐interval WMH change and cognitive performance in population‐based cohorts remain incompletely defined.
