Abstract:

In this paper, the influence of plastic deformation on the rebound behaviour of spheres during oblique impacts with a substrate at various impact angles is analysed using Finite Element Methods (FEM). Both oblique impacts of the elastic spheres with an elastic-plastic substrate and those of an elastic-plastic sphere with an elastic substrate are considered. For each impact case, impact angles ranging from 0° to 85° are specified by either keeping the impact speed constant, i.e, changing impact angle will vary both the normal impact velocities and tangential velocities, or keeping the normal im

Abstract:

Cutterheads equipped with picks are commonly used for mechanized excavation in civil and mining industries. Attack, tilt and skew angles are three key parameters that affect the performance of the picks and the cutterheads. Therefore, it is necessary to optimize these three types of angles. The optimal values of these angles are often obtained through theoretical analysis and/or tests. However, because these angles are set sequentially during manufacturing and one angle which is set before another will be changed by the latter, the final angles of a pick can be different from its designed valu

Abstract:

Low-speed oblique elastic impacts frequently occur in heat exchangers and other equipment having loosely supported tubes or pipes. In order to experimentally study friction during such impacts, a pendulum-type impact apparatus was developed. A hardened steel sphere at the end of the pendulum collides with a flat steel surface for a range of approach velocities and angles. The present investigation examined eight velocities from 8 to 93 mm/s and impact angles (measured from the common normal) of 0 to 75 deg for each velocity. The normal and tangential contact force waveforms were measured using

Abstract:

Blunt impact trauma to the patellofemoral joint during car accidents, sporting activities, and falls can produce a range of injuries to the knee joint, including gross bone fracture, soft tissue injury, and/or microinjuries to bone and soft tissue. Currently, the only well-established knee injury criterion applies to knee impacts suffered during car accidents. This criterion is based solely on the peak impact load delivered to seated cadavers having a single knee flexion angle. More recent studies, however, suggest that the injury potential, its location, and the characteristics of the damage

Abstract:

The erosion behaviors of a hydraulic concrete under high-speed abrasive waterjets at different impact angles were investigated in this paper. The worn surfaces were observed by a scanning electron microscope (SEM). It was found that the defects in the matrix are often the nucleation sites of the microcracks during the erosion. The erosion mechanisms of hydraulic concrete at different impact angles were discussed. The results showed that the erosion process is mainly the microcutting at small impact angles, but peeling off at large impact angles, or mixed mechanism, i. e. microcutting and peeli

Abstract:

Engineering rock mass is normally subject to cyclic–dynamic disturbances from excavation, blasting, drilling, and earthquakes. Natural fractures in rock masses can be reactivated and propagated under dynamic and static loadings, which affects the stability of rock mass engineering. However, fractured rock mass failure induced by cyclic-impact disturbances is far from clear, especially considering varying angles between the rock mass and the direction of impact loadings. This work investigated rock deformation and failure characteristics through cyclic impact tests on granite samples with crack

Spherical impact indentation tests with different impact angles (90°, 60°, 45°, and 30°) was carried out to understand the effect of impact angles on damage degree of cement clinker. A linear rail which can adjust angle to alter impact velocity was used to guide the slipping impact head to impact the sample. The different steel wedge was used to change the impact angle. It is found that the area of damage surface for cement clinker is most serious the peak impact force for surface damage decreases but the contact indentation becomes longer with decreasing impact angle when the impact angle is

AbstractWe present findings from an experimental investigation into the impact of solid cone-shaped bodies onto liquid pools. Using a variety of cone angles and liquid physical properties, we show that the ejecta formed during the impact exhibits self-similarity for all impact speeds for very low surface tension liquids, whilst for high-surface tension liquids similarity is only achieved at high impact speeds. We find that the ejecta tip can detach from the cone and that this phenomenon can be attributed to the air entrainment phenomenon. We analyse of a range of cone angles, including some og

This study aimed to investigate the impact of a horse hoof wall on three solid surfaces: steel, concrete and asphalt. Impact experiments were conducted for different impact angles and different initial impact velocities. The effect of impact surfaces, impact angles and initial impact velocities on the coefficient of restitution and the effective coefficient of friction were tested using one-way ANOVA. Analytical and numerical modeling of the impact were developed. The impact interval was divided into two phases: compression and restitution. For compression, a contact force with a damping term

In tidal two-way contra-rotating units, significant differences in performance often occur when arranging the front and rear impellers, which requires an optimized design of the impellers. To solve this problem, by reducing the blade inlet and outlet angles, the impact of different blade angles on the performance of two-way pump–turbines and the internal flow was explored, and the effects of the blade inlet angle of the impellers on the performance of the counter-rotating pump were obtained.

We comment on these points from two angles: (1) human–system interaction and (2) organisational reliability. Stressing differences in context and in resulting implications, we strongly recommend that the upcoming invasion of work organisations by autonomous systems should be viewed (also) through the lens of the social sciences.

Abstract:

AbstractTo meet the demands for flexible assembly technology, an aerodynamic feeding system has been developed. The system autonomously finds the optimal configuration of four parameters – two angles of inclination, nozzle pressure and component speed – using a genetic algorithm, which has been presented in earlier work. To increase the flexibility of the feeding system, an actuator was implemented, that enables the variation of the nozzle position orthogonally to the moving direction of the components. This paper investigates the effects of the more flexible flow against the components on their behavior when passing the nozzle. Additionally, the nozzle position was implemented into the genetic algorithm as a fifth parameter. Therefore, the impact of the enlargement of the solution space of the genetic algorithm due to the implementation of a fifth parameter is investigated in this paper as well.

Abstract:

AbstractThe chapter explores the nature of higher education in post-Soviet Armenia given the factors prevailing in the system—historical, political, socio-economic and international. Of particular interest is the exploration of the higher education system structure reflected by social needs, economic demands and political goals. Supported by a holistic theoretical framework underpinning three angles of analysis—horizontal and vertical diversity, external diversity as well as the organisational interrelationships—the analysis endeavours to reveal the driving forces that shaped post-Soviet Armenian higher education, the inter-influence that occurred as a result of changes taking place at the macro and micro levels of the higher education system as well as the impact of those changes on the performance of the Armenian HE in general. The results of the analysis are two-fold. First, throughout the decades the Armenian higher education has made major strides and evolved from a uniform into a diverse system responding and accommodating the diverse needs of the society. Second, albeit the strong desire and much investment in the system through a diversity of channels to make the system internationally visible, still more investments are to be made to achieve the desirable goal of international visibility while facing the challenges related to the Soviet legacy, current policymaking and implementation methodology, in particular.

Abstract:

In this paper, a compound pendulum impacting a granular media is studied and the influences of initial impact velocity and impact angle are examined. The resistance forces are studied as the sum of a dynamic frictional force (velocity dependent) and a static resistance force (depth dependent). The penetrating angle is increasing with initial impact velocity as expected. However, the stopping time is decreasing with initial impact velocity for all initial impact angles in our system.

Abstract:

If policymakers or researchers aim to improve an intervention, scale it up, or assess why it works and for whom, then focussing solely on direct outcomes is not enough. There are several ways in which evaluations can go beyond traditional outcome measurement and explore the underlying drivers of impact and the behaviours of beneficiaries and non-beneficiaries. - Measurement goes hand in hand with developing a theory of change, and the two work best when they evolve jointly: new (and better) measurements could allow the consideration of more flexible and realistic theories, while theory informs

Abstract:

As research continues into how fire department interventions affect fire dynamics in the modern fire environment; questions continue to arise on the impact and implications of interior versus exterior fire attack on both firefighter safety and occupant survivability. Previous research into various types of fire ground ventilation, flow paths, and exterior fire streams has provided the fire service with an increased understanding of fire dynamics. However, in some instances, the information from the studies may not support current, experienced-based practices. This gap between the research to d

Abstract:

Over the last two decades, an increasing number of highway construction and maintenance projects in the United States have been completed at night to avoid or alleviate traffic congestion delays. Working at night entails several advantages, including lower traffic volumes, less impact on local businesses, cooler temperatures for equipment and material, and fewer overall crashes. Although nighttime roadway operations may minimize traffic disruptions, there are several safety concerns about passing motorists and workers in the nighttime work zone. For instance, improper lighting arrangements or

Abstract:

In recent years, innovative mobility and shifts in travel and consumption behavior are changing how people access and use the curb. Shared mobility—the shared use of a vehicle, bicycle, scooter, or other mode—coupled with outdoor dining, curbside pick-up, and robotic delivery are creating new needs related to the planning, management, and enforcement of curb access. This study examines curb planning and management from several angles, such as safety, social equity, and multimodal connections. This research employs a multi-method approach to identify the changing needs for curb space management

Abstract:

Construction work zones for roads pose significant safety challenges for drivers and workers, which can lead to accidents, injuries, fatalities, and property damage. Enhancing construction work-zone safety requires an understanding of the factors influencing accidents and fatalities and an evaluation of existing safety and traffic-management measures. The objective of this study was to improve work-zone safety for roadways, by connecting passive material sensing in the road with vehicle communication systems. A review of the main roadway work-zone safety literature found driver behavior, traff
