Process‐induced residual stresses in compression molded UHMWPE
Polymer Engineering & Science, 1999AbstractNon‐isothermal cooling during processing causes the development of residual stresses, which are analyzed for compression molded UHMWPE, and affects the dimensional stability. The development of thermal residual stresses was predicted using an incremental stress analysis that included temperature‐dependent material properties. Strain gauges were

Compressive Residual Stress on Fatigue Fractured Surface
1989X-ray fractography is a technique for analysing the cause and mechanism of fracture from the information obtained by X-ray irradiation on the fractured surface. It has been shown that a good correlation exists between the residual stress or the half value breadth of diffraction profile and the stress intensity factor that had caused the fracture. X-ray

Wear of 3Y–TZP containing compressive residual stresses at the surface
Journal of Materials Science, 1999Tetragonal zirconia polycrystals doped with 3 mol % yttria (3Y–TZP) was heat treated to stimulate the tetragonal to monoclinic phase transformation in order to induce compressive residual stresses at the surface. Pin-on-disc wear tests were performed at different sliding speeds to evaluate the wear behavior of treated and untreated materials.

Stability of Compressive Residual Stress Introduced by HFMI Technique
Volume 4: Materials Technology, 2018Fatigue strength of welded structures is affected by welding residual stresses, which influence crack propagation at weld toe or root, considerably reducing the effectiveness of the structure and increasing its construction and maintenance costs. A mechanical post-weld treatment such as HFMI (High-Frequency Mechanical Impact) has been found to exhibit ...

Use of Cavitating Jet for Introducing Compressive Residual Stress
Journal of Manufacturing Science and Engineering, 1999In an attempt to strengthen the surface of materials, the potential of using a cavitating jet to form compressive residual stress has been investigated. Introducing compressive residual stress to a material surface provides improvement of the fatigue strength and resistance to stress corrosion cracking. In general, cavitation causes damage to hydraulic

Surface Cracking in Layers Under Biaxial, Residual Compressive Stress
Journal of the American Ceramic Society, 1995Thin two‐phase, Al 2 O 3 / t ‐Zr(3Y)O 2 layers bounded by much thicker Zr(3Y)O 2 layers were fabricated by co‐sintering powders ...

Effects of compressive residual stress on the morphologic changes of fibroblasts
Medical & Biological Engineering & Computing, 2009Recently, the term tensotaxis was proposed to describe the phenomenon that tensile stress or strain affects cell migration. Even so, less attention has been paid to the effects of compressive stress on cell behavior. In this study, by using an injection-molded method combined with photoelastic technology, we developed residual stress gradient ...

Fracture statistics of ceramic laminates strengthened by compressive residual stresses
Journal of the European Ceramic Society, 2008Abstract Ceramic multilayer composites have been developed in recent years to enhance toughness and reliability of ceramics. It has been demonstrated by theoretical as well as experimental means, that surface compressive stresses protect the composite against the negative action of surface flaws. The behaviour of an alumina–alumina/zirconia laminate

Generation of compressive residual stresses by high speed water quenching
International Heat Treatment and Surface Engineering, 2010AbstractAccording to the literature, rapid water quenching can create compressive residual stresses (RSs) near the surface and thereby produce a significant increase in the fatigue limit. This technique is called 'intensive quenching'. In the present paper, some results from a research project will be presented.

Toughening of thermosets by the creation of residual compressive stresses
Journal of Applied Polymer Science, 2006AbstractThe toughening of thermosets through the creation of residual compressive stresses around microspheres was studied. Expandable, hollow microspheres containing gas with heating were used for the creation of residual compressive stresses. Microscopic compressive residual stresses in the vicinity of the crack tip were graphically analyzed and ...
