In this paper, the effects of different loading paths axial tension and external pressure on collapse sandwich tubes are studied by experiments finite element models. The difference two is investigated. Eight were carried out to study influence pipeline under same geometric material parameters. Parameterization studies have been out, results in good agreement with experimental results. test sho...

Crashworthiness studies are in high demand for designing transportation systems. Energy absorption capability in vehicle collisions is an important parameter for the development of passive safety systems dealing with the protection of passengers and cargo departments in the event of an accident. Protective structures, which contribute significantly to the crashworthiness capability of automotiv...

Steel piles below high-rise buildings may carry larger varying axial force generated by the overturning moment than those low- or medium-rise buildings. On top of that, subgrade lateral stiffness reduces drastically due to soil liquefaction during a significant earthquake. pile’s horizontal strength decrease lower position inflection point. In this paper, centrifugal tests superstructure with h...

Progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. Both General Services Administration (GSA) and United States Department of D...

Abstract Predicting the response of swirling flames subjected to acoustic perturbations poses significant challenges due complex nature flow. In this work, effect swirl number on Flame Describing Function (FDF) is explored through a computational study four bluff-body stabilised premixed with numbers ranging between 0.44 and 0.97 at forcing amplitudes 7% 25% mean bulk velocity. The LES model us...

Aims. Updated data of the 153 Galactic globular clusters are used to readdress fundamental parameters of the Milky Way, such as the distance of the Sun to the Galactic centre, the bulge and halo structural parameters, and cluster destruction rates. Methods. We build a reduced sample that has been decontaminated of all the clusters younger than 10 Gyr and of those with retrograde orbits and/or e...

Axial length (AL) is a significant indicator of eyeball development, but reports on the overall status of axial development in congenital cataract (CC) patients and its relationship with patient demographics, such as age, sex, and laterality, are rare. We prospectively investigated the AL of 1,586 patients ≤ 18 years old and undergoing cataract surgery in China from January 2005 to December 201...

Axial algebras are a recently introduced class of non-associative algebras, where the focus is on special idempotents called axes and properties algebra specified in terms fusion law which governs how eigenvectors an axis multiply. Jordan Majorana (including Griess for Monster) examples. Ivanov shape algebra, configuration 2-generated subalgebras arising that algebra. In order to generalise t...

Thick, slow-moving block-lava flows are associated with extrusive activity in dacitic systems, where lava-core depressurization during flow-front collapse generates devastating block-and-ash flows. Dimensional and rare thermal data collected during January 2000 for an active dacitic block flow at Santiaguito (Guatemala) provide insight into cooling and emplacement mechanisms. Flow velocity was ...
