Stress relief cracking in creep resisting low alloy ferritic steels.
Early investigations of the phenomenon of Stress Relief Cracking in low alloy steels suggested that the observed failure along prior austenite grain boundaries was in large part promoted by the relative strengthening of the grains with respect to the grain boundaries, during the stress relieving …

Thermo-mechanical stress relief analysis in PMMA and 6000 series aluminum
Stress relief of materials produced in bulk is a key part of the manufacturing process. The most common kinds are either thermal or mechanical and are commonly applied to commercial metal alloys. A third type, thermo-mechanical, utilizes thermal gradients to induce residual stresses of an equal and …

Laboratory and Field Evaluation of Performance-Engineered Stress Relief Courses in Nevada
… resulted in the development of an engineered stress relief course (ESRC) with performance-based mix design specifications to be used as an interlayer between the existing AC layer and the AC overlay. Consequently, the ESRC was used in three NDOT demonstration projects constructed in 2015, …

Susceptibility of creep aged material to stress relief cracking during repair welding
… zone is discussed with emphasis on the residual stresses that develop in this zone. The mechanical properties of the heat-affected zone are also investigated. This includes the tensile, toughness and hardness properties as well as inspecting the relevant microstructures. The effect of post weld …

The central role of stress relief in video gaming motivations and preferences
… popular gaming network “Steam”, and finds that stress relief is a primary motivation for engaging in the immersive worlds of video games. Previous research has indicated three underlying factors of Immersion, Achievement and Socialising which replicated across three comprehensive studies of 480 …

Use of strigolactone for stress relief and increased productivity in high-yielding environments
Due to the projected global population increase, food production will need to increase by 60 percent. Of this food production increase, 90 percent is projected to originate from intensified management and increases in yield. Producers will need to utilize new technologies in order for food …

Optimal Time and Temperature for Maximum Moment and Springback and Residual Stress Relief of Stainless Steel Wire
… It appears that the degree of improvement and stress relief obtained is time and temperature sensitive. Low temperature stress relieving appear to be of definite benefit and it certainly compliments what is known about sensitization phenomena. There was no uniform increase in springback as the …

The Role of Horizontal Stress in the Formation of Valley Stress Relief Features in Flat-Lying Sedimentary Rocks
… the existence of a regional horizontal stress, well in excess of gravitational considerations, will is presented. This evidence will include a database of in situ measurements so that an estimate of the magnitude of this stress can be obtained for the analysis to follow. Second, a …

Stress relief: Exercising Lewis acid catalysis for donor-acceptor cyclopropane ring-opening annulations, a basis for new reaction methodologies
… six chapters: (1) an introduction, paradoxical stress and molecular strain’s utility in synthesis; (2) annulation reactions for the formation of heteroaromatic cyclohexenones; (3) hydropyrido[1,2-a]indole formation via an In(III)-catalyzed cyclopropane ring-opening/Friedel-Crafts alkylation …

Investigating packaging effects on bandgap references
… used in LTC switching regulators. Packaging stress causes a mean offset and room temperature distribution widening of the bandgap reference output voltage, as well as inconsistent temperature characteristics. Bandgap references with and without a proprietary stress-relief mechanism were …

A new method of termination for heavy-duty synthetic rope fibres
… inside or very close to termination due to high stress concentration areas. The new method, "The Vaseghi Stress Relief Socket", has been proposed to improve the high stress concentration areas inside sockets and move failure points along the rope. The new method has increasedthe tensile …

Measuring absence cultures: an examination of absence perceptions of males and females
… split into three dimensions: Personal Health, Stress Relief, and Family Responsibility (Nicholson and Payne, l9S7). One hundred and two employees of a large southeastern university were used as subjects. They were asked to give their own opinion and their opinion of their organization's view …

Tensile relaxation of bonded concrete overlays
… shrinkage in bonded concrete overlays can cause stress build up, cracking and even debonding. Tensile relaxation is the main mechanism of stress relief in concrete overlays. This results in less possibility of cracking and debonding. The research described in this study presents an analytical …

The cultural ecosystem services provided by a semi-natural suburban wetland
… Suburban wetlands are venues for relaxation, stress relief, and connecting with nature. Residents have strong positive feelings toward suburban wetlands, and a strong preference for incorporating natural wetland elements into suburban developments. Incorporating natural wetlands contributes to …

DISCLOSURE DECISION MODEL: ANALYSIS OF PRIVATE AND WORKPLACE FRIENDSHIPS
… tended to use relationship development and stress relief disclosure goals with both their private friends and workplace friends than social control, identity clarification, or seeking approval goals. Additionally, the only disclosure goal that predicted disclosure depth was social control. …

Nonlocalized faulting in a thick lithosphere : application to lunar contraction
… the entire lithosphere and thus enabling large stress relief and large displacements. For a thick elastic lithosphere the mode of faulting is less localized and many faults form in the upper part of the lithosphere, each with small displacements. Furthermore, localization in a thin lithosphere …

The role of reactance and positive emotions in persuasive health messages: refining the theory of psychological reactance and the politeness theory and testing the theories of positive emotions
… in a weekly exercise routine and the "stress relief" study encouraged practicing meditation for general mental/physical health. One major contribution of this study is that this study extended the Theory of Psychological Reactance by incorporating the notion of threats to identity based …
