Abstract:

The structural parts of construction machinery mostly fail due to impact load, but current research on the failure behavior of the impact load has not established a complete theoretical system. Based on wave theory and fracture mechanics, this paper analyzed the wave behavior of shock stress waves and established a model of shock stress wave propagation. Given the dynamic response behavior of the stress and strain field at the crack tip, dynamic fracture mechanics theory was used to solve the dynamic fracture strength stress factor and evaluate the dynamic fracture performance of the structure

Abstract:

A finite element analysis was used to investigate layer waviness effects in flat compression-loaded composite laminates. Stress distributions in the vicinity of the layer waves as well as the locations and modes of failure were investigated. Two layer wave geometries were considered, each modeled within an otherwise wave-free thermoplastic composite laminate. These two wave geometries, classified as moderate and severe, corresponded to layer waves fabricated in actual laminates and tested under uniaxial compression loading. Material nonlinearities obtained from intralaminar shear and 0 and 90

Abstract:

The numerical simulations of the flow around different pillars acted by the cnoidal internal waves have been made by building numerical wave flume based on FLUENT software. The cnoidal internal wave was created by using the push-pedal method, and the free surface was tracked by using VOF (volume of fluid) method. The three-dimensional different amplitude and period cnoidal internal waves were simulated. The inertia force and viscous force trends were analyzed, and for different pillars the total wave force were compared. There were some significance for stress analysis of the offshore terminal

Abstract:

Absolute stress in structural steel members is an important parameter for the design, construction, and servicing of steel structures. However, it is difficult to measure via traditional approaches to structural health monitoring. The ultrasonic time-of-flight method has been widely studied for monitoring absolute stress by measuring the change in ultrasonic propagation time induced by stress. The time-of-flight of the two separated shear-wave modes induced by birefringence, which is particular to shear waves, is also affected by stress to different degrees.

Abstract:

The scarcity of materials due to the impact of the pandemic has caused the price of shipbuilding materials is increased and the production costs to become more expensive. So, optimization steps need to be taken to reduce production costs but still ensure the quality of the coal carrier pontoons. One of the optimization steps that can be done is by changing the frame distance. In this study, two variations of the frame distance, 600 and 650 mm, will be carried out to obtain the optimal value from the initial design of 610 mm.

Abstract:

Water hammer is defined as a sudden increase in pipe pressure, which results in pressure waves that travel along the pipe at sonic velocities. In the wake of the pressure wave, dynamic stresses are created in the pipe wall, which contribute to pipe failures. A finite element analysis computer program was used to determine the three-dimensional dynamic stresses that result from pipe wall vibration at a distance from the end of a pipe, during a water-hammer event. The analysis was used to model a moving shock wave in a pipe, using a step pressure wave. Both aluminum and steel were modeled for an

Concrete is a typical kind of rate sensitive material. In this paper, the concrete specimens were tested in the SHPB experiment system. Based on H-J-C constitutive model, the SHPB experiment was simulated by LS-DANY. The stress-strain curves which were gat from numerical simulation in the LS-DANY were compared with the stress-strain curves which were gat from SHPB. The results showed that the H-J-C constitutive could simulate the dynamic characteristics of concrete both under room temperature. The result also showed that the concrete was strain rate sensitive.

Abstract:

The first step in many mining operations is blasting, and the purpose of blasting is to fragment the rock mass in the most efficient way for that mine site and the material end use. Over time, new developments to any industry occur, and design and implementation of traditional techniques have to change as a consequence. Possibly the greatest improvement in blasting in recent years is that of electronic detonators. The improvements related to safety and increased fragmentation have been invaluable.

Rock slope failures leading to rock falls and rock slides are caused by a multitude of factors, including seismic activity, weathering, frost wedging, groundwater and thermal stressing. Although these causes are generally attributed as separate causes, some of them will often act together to cause rock slope failures. In this work, two of the above factors, seepage of water through cracks and crack propagation due to the after effects of blasting are considered. Their combined impact on the development of rock falls and rock slides is modeled on ANSYS workbench using the Bingham Canyon mine sl

The variability of the nearshore wave climate is investigated via the analysis of over 10 years of Acoustic Doppler Current Profiler (ADCP) data from a gauge deployed at Melbourne Beach, FL. Examples of large yearly variability in the significant wave height, peak period, mean direction and energy distribution are found in the data. Estimates of the averaged spectra for the entire record show that the average wave energy is distributed almost symmetrically with the peak being close to shore-normal. It was expected that the peak would be shifted towards the north of shore-normal considering net

Cardiovascular disease remains a major cause of mortality and morbidity and is underpinned by Oxidative stress, within which, inactivation of nitric oxide (NO) by superoxide (SO) and other reactive oxygen species is characteristic. Two major enzyme systems are implicated within oxidative stress; NAD(P)H oxidase and endothelial nitric oxide synthase (eNOS). eNOS generates NO while at the same time, and within the same cells, NAD(P)H plays a powerful role in the generation of SO. Evidence is accumulating that polymorphisms of the genes encoding these enzyme systems may play an important role in

Abstract:

This report presents laboratory evaluations of the effectiveness of geosynthetics in stabilizing unbound aggregate layers and develops design guidelines for using geosynthetic-stabilized pavements in Illinois. The research focused on quantifying benefits from geosynthetic mechanical stabilization and incorporating those benefits into pavement analysis and design procedures. An experimental program was conducted, including laboratory triaxial testing and large-scale test bed evaluations. Twelve geosynthetic products, including ten geogrids (integral or punched and drawn, welded, and woven) and

Abstract:

This paper analyzes the evolution of the gender wage gap in Chile during the period 1992 to 2003 using the decomposition approach developed in Ñopo (2004). This approach, which decomposes the wage gap into four additive elements, stresses the need for comparisons inside the common support for the distributions of observable characteristics of individuals. Also, it allows an analysis of the distribution of unexplained differences in wages (not only the averages). The results suggest that, besides the high educational attainment of females, there are noticeable gender wage gaps in Chile favoring

Abstract:

This report documents the flow failure of the Las Palmas tailings dam that was induced by the 27 February 2010 Maule Chile M8.8 earthquake. The Las Palmas site is located in Central Chile in Region VII near the town of Talca. Construction of the tailings dam occurred between 1998 as part of a gold mining operation and was no longer in active use. The ground shaking from the earthquake induced liquefaction of the saturated tailings material and resulted in a flow failure that ran out upwards of 350 m, flowing downslope in two directions. This report is broken into three sections: A summary of t

Abstract:

Trucks serve significant amount of freight tonnage and are more susceptible to complex interactions with other vehicles in a traffic stream. While traffic congestion continues to be a significant ‘highway’ problem, delays in truck travel result in loss of revenue to the trucking companies. There is a significant research on the traffic congestion mitigation, but a very few studies focused on data exclusive to trucks. This research is aimed at a regional-level analysis of truck travel time data to identify roads for improving mobility and reducing congestion for truck traffic. The objectives of

Abstract:

Background: Public behaviour and the new hostile threats • Civil contingencies planning and preparedness for hostile threats requires accurate and up to date knowledge about how the public might behave in relation to such incidents. Inaccurate understandings of public behaviour can lead to dangerous and counterproductive practices and policies. • There is consistent evidence across both hostile threats and other kinds of emergencies and disasters that significant numbers of those affected give each other support, cooperate, and otherwise interact socially within the incident itself. • In emerg

Abstract:

The influence of fathers on child experiences and outcomes has been given much less attention in international and Irish research than the influence of mothers (Fitzgerald et al., 2020). The Growing Up in Ireland (GUI) study has collected very detailed information from fathers throughout the different waves of the study which can be used to address this gap. This report uses data on the younger GUI cohort, Cohort ‘08, who were born in 2008 and were nine years of age in 2017. It documents the nature of father-child interaction and the quality of father-child relationships from infancy (nine mon

Abstract:

The large-opening drum-honeycomb-type quad-strut suspend-dome structure is a new type of suspend-dome structure, which was improved from the traditional cable dome structure. It replaces the top chord of the cable dome with seamless steel pipes. The structure combines the characteristics of the suspend-dome and the cable dome. The bottom chord nodes connects four struts, two inclined cables and one ring cable. The Ansys finite element model is established to analyze the influence of initial prestress, rise-span ratio, thickness-span ratio, opening span and bottom chord arrangement schemes on t
