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

В силу различия коэффициентов термического расширения и эффективных модулей упругости материалов волокна и матрицы в композитах в ходе отверждения от высокой температуры изготовления до комнатной возникают концентрации локальных напряжений. Для оценки влияния остаточных термических напряжений на распределение локальных напряжений в композитах разработали высокоточную микромасштабную модель. Полученные численные результаты показали, что остаточные термические напряжения не вызывают пластические деформации в матрице.

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

Résumé :

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

The effect of specimen size on the parameters of the damage model were investigated by using the test results.

The present study seeks to integrate findings from these two research traditions and extend our understanding of the stress process by investigating the possibility those variations in sourc

This superposition of loads leads to fatigue failure at the stress peaks.

Abstract Stress corrosion cracking and corrosion fatigue are two failure mechanisms that have much in common: a susceptible metal, a corrosive environment, and surface stress — specifically surface tensile stress. Both mechanisms are usually accelerated by increasing temperature. They differ primarily in the fact that stress corrosion cracking results from static tensile stress (either residual or applied but, more often, both) and corrosion fatigue results from dynamically applied tensile stress, often superimposed upon residual tensile stress.

Résumé :

The goal of this project was to develop flow charted decision processes for operators to determine when ILI is appropriate and recommended. Two initial tasks developed the background material needed for developing the decision processes. Task 1 is a review of publicly available and industry research reports pertaining to the linkage between susceptibility to crack-related failure and performing ILI. Primary references are the results from industry work that informed the development of TTO5 and the development of other industry guidance documents. Task 2 is a survey of operators to understand t

Résumé :

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

Résumé :

Environmental cracking processes are caused by the synergistic interaction of a corrosive environment and applied service stress (mechanical contribution) with a susceptible pipeline material. Stress corrosion cracking (SCC) is one form of environmental cracking. Current understanding of the processes associated with SCC suggests that cracks proceed through a continuum of events leading to final failure. In the "life" of a crack, cracks initiate, proceed through a period of growth, link with other cracks to produce a critical defect size that can then cause the failure of the pipeline. The rel

Résumé :

This report is an updated version of the original engineering design guide published in 1995 by the Pipeline Research Committee (PRC) of the American Gas Association. As with the original document, it is intended to serve as a step by step guide for engineers engaged in the evaluation, design, and management of natural gas pipeline construction by horizontal directional drilling (HDD). Topics covered include a description of the HDD process, technical feasibility and cost considerations, surface and subsurface site investigations, drilled path design, steel pipe installation and operating stre

Résumé :

Grinding is an accepted repair method for stress corrosion cracking (SCC) on buried pipelines. Grinding is routinely performed while the pipeline remains in service (i.e., pressurized and flowing). When grinding on a live pipeline, there is a risk that the pipe wall will rupture, either by reducing the wall thickness to below that which is appropriate for the operating pressure or by causing the cracking that is being removed to become 'critical' or unstable as the result of increased local stresses, etc. This project involved a review of current limits, practices, and previous work relevant t
