Résumé :

The Mg-5Zn-2.5Er matrix composite reinforced with the in-situ synthesized Mg2Si second phase particles was fabricated via repeated plastic working (RPW) process. The microstructures and the nanocrystals in the composite have been investigated using transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HREM) and energy dispersive X-ray (EDX). Great deals of nanocrystals were found in the matrix, and they were around the in-situ synthesized Mg2Si. The HREM analysis showed that the size of nanocrystals was in the range of 5-10 nm, and the difference in their cr

Résumé :

Using the COMSOL MULTIPHYSICS software, the problem of the stress-strain state of a steel wire during drawing is solved by the finite element method. A special contact layer is introduced to describe the contact between the wire and the matrix. It consists of a material whose modulus of longitudinal elasticity in the direction perpendicular to the contacting parts coincides with the modulus of longitudinal elasticity of the matrix or wire, and in the other direction is small, as is the shear modulus. During the calculation, the fields of radial stresses, axial stresses and equivalent stresses

Résumé :

ABSTRACTA technique for inverting residual stress based on a theory of acoustoelasticity is presented. A general incremental constitutive relation is first derived for a pre-stressed material subjected to an additional infinitesimal elastic deformation. The theory is then employed on using ultrasonic means to evaluate residual stresses of residually stressed materials. The residual stresses are assumed to be homogeneous in materials as usual. The only major assumption in this formulation is that the additional deformations caused by ultrasonic evaluating process are infinitesimal and elastic.

Résumé :

Shade trees are subjected to a wide variety of environmental stresses which decrease growth and cause injury and mortality. Although trees often are classed as either stressed or unstressed, all trees are periodically stressed by unfavorable environmental conditions above or below ground, and often both. Exposure of trees to some stresses also predispose them to the effects of other stresses. Healthy trees require adequate supplies and balances of carbohydrates, growth regulating hormones, water, and minerals. Environmental stresses, alone or in combination, reduce tree growth by setting in mo

Longitudinal critically refracted (LCR) waves are considered bulk longitudinal waves and penetrate into an effective depth beneath the surface parallel to the material surface. Such LCR waves can be employed to measure residual stresses because the acoustoelastic effect is the basis for ultrasonic residual stress measurements. This effect is described by the relationship between change of wave travel time and stress applied when such waves propagate in a stressed medium. In this paper, stresses applied in a rail were evaluated by using a developed LCR probe. With this transducer, it was verifi

Résumé :

Stress is one of the most important physical indexes reflecting the mechanical behavior of concrete structures. In general, stress in structures cannot be directly monitored and can only be estimated through an established model of stress and strain. The accuracy of the estimated stress depends on the rationality of the established model for stress and strain. As the strain measured by sensors contains creep, shrinkage, and elastic strain, it is difficult to establish an analytical model for strain and stress. In this paper, a statistical inverse method was utilized to estimate the stress in c

Introduction. The contact area of concrete gravity dams is of vital importance. Substantial temperature gradients and tensile stresses can arise in the process of concrete casting and thermal regime creation; they can cause thermal cracking. The practice of monitoring the construction and operation of concrete gravity dams has identified frequent vertical cracking along and across the dam axis, which can have an adverse impact on structural behaviour. Despite the large number of research works, some of which are mentioned in the work, the extent of influence of the modulus of elasticity in the

Résumé :

Bent steel reinforced concrete structures are usually structures for overlap or covering buildings and constructions for various functional purposes. Pre-stresses in structures of this type can be created by installing additional pre-stressed reinforcing bars in the stretched cross-sectional area, which, along with increasing the load-bearing capacity and stiffness of the floors, requires additional material costs and the installation of these bars. Creating initial stresses in building structures from their own weight greatly simplifies the process of pre-stressing due to the unnecessary cost

During the fermentation process, yeast cells face different stresses, and their survival and fermentation efficiency depend on their adaptation to these challenging conditions.

To explore this, we exposed a multi-stress-tolerant strain (BT0510) to different consecutive stresses to globally explore a common response, focusing on the genes induced in both stresses.

Compressive stresses can be generated in the stressed areas by means of shot-peening in order to extend the operating limits for a given yield and fatigue strength.

The stresses created in a large sheet, combined with the residual stresses within the glass substrate, are sufficient to propagate a subsurface flaw to form a controlled crack that gives excellent cut quality.

Résumé :

A traversing water jet was used to impact the surface of 1100 series aluminum specimens in an effort to generate compressive residual stresses on the surface. Stresses induced by the water peening operation were measured using X-ray diffraction, and compressive stress increases as large as 60 percent of the monotonic yield strength resulted. Surface roughness and hardness were also measured. Finite element modeling of a stationary water jet impinging on an elastic-plastic half-space was performed to characterize the water peening process. Surface residual stresses were found to be a result of

Résumé :

Abstract Cells are frequently exposed to a wide variety of stresses that perturb cellular fitness. Stressed cells autonomously drive the defense mechanism to maintain their homeostasis, such as DNA repair program upon DNA damage and chaperone induction and protein degradation pathway upon protein misfolding. However, how cell-to-cell interaction contributes to the maintenance of cellular fitness has been elusive. Here, we show that macrophages interact with proteotoxically stressed cells and promote their proteostasis. Cells undergoing protein aggregate accumulation are detected by macrophages

Résumé :

The aim of this paper is to compare von Mises stress levels and displacements between two possible designs of a class II Kennedy unilateral removable partial denture. Finite element analysis was used to compare two unilateral class II Kennedy removable partial dentures replacing a mandibular second premolar, and first and second molars and with the same design, except a distal implant. The 3D model was created for a mandibular RPD with three artificial teeth and double ball attachment on the abutment teeth and a horizontal ball attachment for the implant, using Autodesk Inventor 2022 software.

Résumé :

Sandwich panels can be manufactured in many ways like lamination press, closed mold fabrication, and vacuum bag compaction. During manufacturing, the core and the sheets are attached under certain applied pressure and temperature, associated with a deformation and stress remaining in the sandwich core. This study presents an evaluation of the compressive residual stress effect of the core which occurs during the localized shock loading at the mid-span of a clamped sandwich plate. We simulate such a square lattice core sandwich plate by commercial finite element code, ABAQUS/Explicit. We apply

Résumé :

In the present work, Pyrowear53 steel was subjected to the impulse carburizing LPC process. After carburation, the material was quenched and tempered. Postprocessing analyses included the measurement of hardness, carbon content, residual austenite, and residual stresses. The results revealed that the thermochemical treatment resulted in the formation of an approximately 1200 µm wide carburized layer. The results of hardness, carbon content, and residual austenite measurement showed a continuous gradient (drop) in the measured values within the carburized layer. However, the results of residual

Résumé :

Abstract The present investigation deals with the reflection of plane periodic waves incident at the surface of a homogeneous initially stressed transversely isotropic fibrereinforced thermoelastic medium. The wave equations are solved by imposing proper conditions on displacements, stresses and temperature distribution. Numerically simulated results have been depicted graphically for different angles of incidence with respect to frequency. Some special cases of interest have also been deduced from the present investigation

Résumé :

Abiotic stresses reduce crop growth and yield in part by disrupting metabolic homeostasis and triggering responses that change the metabolome. Experiments designed to understand the mechanisms underlying these metabolomic responses have usually not used agriculturally relevant stress regimes. We therefore subjected maize plants to drought, salt, or heat stresses that mimic field conditions and analyzed leaf responses at metabolome and transcriptome levels. Shared features of stress metabolomes included synthesis of raffinose, a compatible solute implicated in tolerance to dehydration. In addit

An analytical review is given on the influence of the stressstrain state on the process of corrosion pitsformation in the process of internal corrosion of the field oil pipelines wall. The views of domestic and foreign researchers on the causes of the corrosion process intensification under the stresses action, as well as on the mechanisms of the stress-strain state influence on the process of pitting formation, are presented. Two main reasons for the intensification of corrosion under the stress-strain state influence are indicated: a decrease in the thermodynamic stability of metals and a de

The effect of processing atmosphere on the microstructure and residual stresses are studied for laser surface hardening on steel samples of grade AISI 4140. Samples were hardened in air, vacuum and inert gas atmosphere (Helium) by means of a stationary laser beam. A high-power diode laser (HPDL) system was used in combination with a custom-designed process chamber. Residual stress distributions in lateral and in depth direction were analysed after laser processing by means of X-ray diffraction according to the well known sin² - method.

Résumé :

The saw stability in operation defines the ability of the saw blade to resist the forces acting on it in the plane of greatest rigidity. The saw can work reliably only in case of maintaining stable balance, which is achieved through the creation of normalized residual stresses in certain zones of the saw blade by different methods. The stresses balance the forces of external influences. Compressive stresses are created in the central part of the blade to make the circular saw operational. These stresses compensate the forces of centrifugal acceleration, temperature heating of individual zones
