Abstract:
The influence of static compressional stress on the anisotropy of piezoelectric ceramics of BaTiO3 and PZT types is considered theoretically and experimentally. Static compression changes the domain structure of piezoceramics. These changes occur due to the reorientation of mostly 90° domain axes. As a result, all the parameters of the material change—elastic, piezoelectric, and dielectric. Some of them increase, and some, on the contrary, decrease. Changes occur in a nonlinear way, and higher-order parameters appear. The relationship between the total volume of the reoriented domains and the

Abstract:
Rubber materials play an important role in robotics, due to their sensing and actuating abilities, that are exploited in soft smart materials endowed with shape-adaptive and electroadhesive properties. The application of an electric field produces non-linear deformation that has been extensively modelled, but is not understood at the molecular level. The symmetric effect (the production of an electric field due to rubber deformation) was recently discovered and explained as follows: rubber surface chemical composition and adsorptive properties change during rubber deformation, allowing the sur

Abstract:
Abstract For decades there has been a debate about the relative effects of dynamic versus static stress triggering of aftershocks. According to the static Coulomb stress change hypothesis, aftershocks should not occur in stress shadows—regions where static Coulomb stress has been reduced. We show that static stress shadows substantially influence aftershock occurrence following three M ≥ 7 California mainshocks. Within the modeled static Coulomb stress shadows, the aftershock rate is an order of magnitude lower than in the modeled increase regions. However, the earthquake rate in the stress sh

Abstract The analysis of static stress changes due to co-seismic dislocations has been widely applied in recent years to study the variation in failure stress on well-known segmented seismogenic faults. These studies assert that earthquakes induce changes in static stress on neighboring faults that may delay, advance, or trigger impending earthquakes. So far, most of the investigations have focused on California strike-slip faults and, more recently, on thrust faults. In this work, we study the static stress changes in an extensional tectonic setting. Following Okada (1992), we calculate stati

Adding mineral admixtures can change the initial static yield stress of the paste by affecting the particle size, particle shape and the charged particles.

In this study, the behavior of each cell after division was tracked by time-lapse microscopic images through 24 hours of culture under a shear stress field. A constant shear stress field was applied to the cells in the Couette flow between the parallel walls: the lower static culture disc and the upper rotating disc. For comparison, four types of cells were used: C2C12 (mouse myoblast), HUVEC (human umbilical vein endothelial cells), 3T3-L1 (mouse adipose progenitor c

ABSTRACT: We performed a study of ultrasonic velocity as a function of stress and stress path using axial and radial ultrasonic P and S-waves. Young's modulus and Poisson's ratio are calculated using these velocities along axial and radial directions. Static elastic moduli are also measured along the same stress and stress path protocol. Effects of pre-existing microcracks in the sample are hypothesized via directional observations of velocity changes as a function of differential stress and mean stress. Dynamic Young's modulus is observed to increase primarily as a function of mean stress, wh

Abstract:
Abstract In a strong electric field, polarizable fluids have a structural transition at a critical shear stress. When there is no flow, polarizable fluids form a body-centered tetragonal lattice which consists of closely packed chains. When the shear stress is increased from zero up to a critical value, the flow (in x-direction) has a flowing-chain (FC) structure, consisting of tilted or broken chains along the field (z-direction). At the critical shear stress, the FC structure gives way to a flowing-hexagonal-layered (FHL) structure, consisting of several two-dimensional layers which are para

Almost 14000 aftershocks have been located in the first six month after the Mw 6.4 Petrinja earthquake of 29 December 2020. Most epicentres lie close to the NW–SE striking right-lateral causative fault, but considerable activity has been recorded in the surrounding area up to about 50 km away. The hypocentres reach depths of over 20 km, with most of activity recorded between the depths of 5 and 16 km. Their spatial pattern reveals activation of a number of smaller faults.

Abstract:
This paper describes a proof-of-concept non-contact strain sensor, using a magnetostrictive Fe-Ga alloy (Galfenol). Magnetostrictive materials demonstrate dimensional changes in response to a magnetic field. In contrast with typical piezoceramic materials, Galfenol is the most ductile of the current transduction materials and appears to have an excellent ability to withstand mechanical shock and tension. Galfenol also exhibits the inverse (Villari) effect: both the magnetization and permeability change in response to an applied stress. Galfenol has low hysteresis loses, less than ∼10% of its t

The Southern Colorado Plateau Inventory and Monitoring Network monitors status and long-term trends in the aquatic macroinvertebrate community and associated habitat in order to track changes in the ecological integrity of stream ecosystems. This report investigates changes in key aquatic macroinvertebrate community indices and physical habitat metrics collected from two long-term monitoring sites on the Mancos River in Mesa Verde National Park, Colorado. Results suggest that both monitoring sites have experienced periods of thermal and hydrologic stress. These stresses occur concurrently and

Abstract:
Large standoff magnetometry is an emerging non-destructive magnetic test method, which is remote, passive, and non-contact. It is based on the inverse magnetostrictive effect and, therefore, has potential for detection of magnetic anomalies produced by elevated stresses in steel pipelines and ferromagnetic structures. Changes in the local pipeline stress state may arise due to corrosion, cracking, mechanical damage, ground movement (geohazards), or external loading. Laboratory measurements were performed on macroscopic steel samples in the elastic stress regime to investigate the potential for

Abstract:
Ferromagnetic pipeline steel may exhibit magnetization, even in the absence of applied magnetic fields, due to remnant fields or the presence of pipe wall stress. Remnant magnetization may be present from previous or existing exposure to a magnetic field, while pipe wall stress induced magnetization can result from line pressure, environmental stresses due to settling or geohazard conditions, and residual stresses due to nonuniform plastic deformation caused by manufacturing processes, installation or operating conditions. The local stress state of the pipeline may also be altered by corrosion

The predicted flow measurement error was compared with the actual flow measurement error.
