Abstract:
Abstract In this study the response of tropical precipitation extremes to warming in organized convection is examined using a cloud-resolving model. Vertical shear is imposed to organize the convection into squall lines. Earlier studies show that in disorganized convection, the fractional increase of precipitation extremes is similar to that of surface water vapor, which is substantially smaller than the increase in column water vapor. It has been suggested that organized convection could lead to stronger amplifications. Regardless of the strength of the shear, amplifications of precipitation

Abstract:
Mechanical removal of oral biofilms is ubiquitously accepted as the best way to prevent caries and periodontal diseases. Removal effectiveness strongly depends on biofilm strength. To investigate the influence of hydrodynamics on oral biofilm strength, we grew single- and multi-species biofilms of Streptococcus oralis J22, Actinomyces naeslundii TV14-J1, and full dental plaque at shear rates ranging from 0.1 to 50 1/sec and measured their compressive strength. Subsequently, biofilm architecture was evaluated by confocal laser scanning microscopy. Multi-species biofilms were stronger than singl

Abstract:
Impact loads in previous research showed to induce brittle responses of statically flexure-critical reinforced concrete (RC) beams designed for ductility. The impact load may produce flexural shear damage modes similar to that observed during quasi-static loads and local shear damage under the impact zone. The occurrence of shear damage modes during impact tests has been investigated extensively, but their effect on the residual quasi-static and dynamic capacity is not fully understood. For this aim, an initial high-velocity impact test initiated severe shear damage to RC beams. The beams were

Aiming at the cyclic impact deformation and failure of tunnel surrounding rock under shear stress, a self-developed rotation-impact simulation test platform was used to determine the number of failures, stress-strain curves, and energy in the process of cyclic impact failure. The failure process of rock under different impact velocities and shear stresses has been systematically studied. Results show that, under the same impact speed, the shear stress will increase with the increase in the rotation speed, but an upper limit will exist.

Abstract:
Polypropylene bead foams were subjected to oblique impacts, in which the material is compressed and sheared. This strain combination can occur when a cycle helmet hits a road surface. The results were compared with simple shear tests at low strain rates, and to uniaxial compressive tests at impact strain rates. The observed shear hardening was greatest when there was no imposed density increase, and practically zero when the angle of impact is less than 15 degrees. The shear hardening appears to be a unique function of the principal tensile extension ratio and is a polymer contribution, wherea

We study axisymmetric deformations of depleted uranium (DU) and tungsten heavy alloy (WHA) rods impacting at normal incidence both a rigid, planar target and a thick, deformable steel target. Each deformable material is modeled as elastic thermoviscoplastic; the flow stress increases with an increase in the effective plastic strain and effective plastic strain-rate but decreases with a rise in the temperature. An objective of this work is to ascertain when and where a shear band, defined as a narrow region of rapid, intense plastic deformation, forms in each material subject to impact loading.

Low-velocity drop-weight impact experiments are conducted to investigate the effect of the STF’s dimensions in a finite volume on the impact behaviour of the STF.

Abstract:
Prolonged sitting has been shown to impair endothelial function in children, yet the mechanisms underlying this remain unclear. In adults, there is a decline in endothelial function, indexed using flow-mediated dilation (FMD), after 1 hour of sitting. When localized heating was used to increase shear stress, the sitting-induced reduction in FMD can be prevented, confirming this decline was shear-stress mediated. The relationship between FMD and shear stress is weaker in children and whether limb heating increases shear stress and FMD in children is unknown. We therefore examined the time-cours

Abstract:
Abstract A series of Taylor rod-on-anvil experiments have been performed to validate the predicted impact velocity fracture threshold and fracture mode of a high hardness armour steel (HHA) obtained through explicit finite element simulations. Experimentally, the rods exhibited principal shear failure, a condition that can be closely linked to adiabatic shear band (ASB) formation in high strength steel. Using a stress triaxiality and Lode angle dependent failure strain criterion (Basaran 3D fracture locus), calibrated from quasi-static mechanical characterisation tests, the simulations were un

Abstract:
Heavy-duty electric vehicles (HDEV) pose challenges to flexible pavements. This study evaluated four Illinois pavement structures to quantify HDEV impacts on pavements. Compounding factors included increases in load and acceleration, which escalated critical strains and reduced repetitions to failure. Various distresses were considered: bottom-up cracking, shear-driven top-down cracking, and shear-driven shoving. A proposed framework is presented, which includes a new metric—e-truck adjustment factor—that enables a full truck comparison of internal combustion engine vehicles (ICs) with HDEVs.

Abstract:
Vibration compaction is the most effective way of compacting coarse-grained materials. The effects of vibration frequency and amplitude on the compaction density of different backfill materials commonly used by INDOT (No. 4 natural sand, No. 24 stone sand, and No. 5, No. 8, No. 43 aggregates) were studied in this research. The test materials were characterized based on the particle sizes and morphology parameters using digital image analysis technique. Small-scale laboratory compaction tests were carried out with variable frequency and amplitude of vibrations using vibratory hammer and vibrato

Full text
Abstract:
The paper addresses slope stabilization through use of deep foundation elements (for simplicity, we refer to them generically as “piles” throughout this paper) and particularly focuses on the efficiency of linear versus staggered arrangements of piles along a slope. The study investigates the impact of pile arrangement on shear resistance, assuming constant soil properties, pile size, and reinforcement. The research employs Slope/W and Group software for slope stability analysis and reinforcement design; however, the analysis procedure detailed in this paper can be applied to other applicable

Full text
Abstract:
Pipeline valve bodies, fittings, flanges, and numerous other components are typically made of cast or forged low-alloy steels. The large wall thicknesses necessitated by the complex shapes of these components usually are not conducive to ductile fracture behavior. Nevertheless, there is a distinct need to have sufficient toughness in such components so that they will not be susceptible to catastrophic failure from defects that may remain after manufacturing and hydrostatic testing. The present practice for controlling toughness in such components consists of specifying arbitrary values of Char

Abstract:
This report describes the design, construction, and shaking table response and computation simulation of a Low Seismic-Damage Bridge Bent built using Accelerated Bridge Construction methods. The proposed bent combines precast post-tensioned columns with precast foundation and bent cap to simplify off- and on-site construction burdens and minimize earthquake-induced damage and associated repair costs. Each column consists of reinforced concrete cast inside a cylindrical steel shell, which acts as the formwork, and the confining and shear reinforcement. The column steel shell is engineered to fa

Abstract:
Mechanical properties of commercially available temporary pavement marking (TPM) tapes and thermoplastic materials used as permanent pavement markings (PPM) were investigated using the non-destructive Tape Drape Test and conventional mechanical testing. The impact of temperature and aging on the adhesion of TPM tapes and thermoplastic PPM applied to asphalt core surfaces with various surface roughness and treatments was determined using a modular peel fixture and shear adhesion tests. The adhesion of TPM tapes to model smooth surfaces decreased as surface temperature was increased from 0 to 40
