We report a method to obtain the stress of crystalline materials directly from lattice deformation by Hooke's law. The lattice deformation was calculated using the crystallographic orientations obtained from electron backscatter diffraction (EBSD) technology. The stress distribution over a large area was obtained efficiently and accurately using this method. Wurtzite structure gallium nitride (...

The aim of this study was to analyse the stress distribution in maxillary canines restored with different post systems and definitive crowns. The models of restored teeth with glass fiber, quartz fiber, titanium posts and crowns were developed with the Finite Element Method (FEM) in order to analyse their stress distribution when subjected to external compressive loads. Von Mises stress distrib...

The present study aims to investigate the analysis of stress, strain, displacement, and electrical potential of a thick hollow cylinder made of FGPM under mechanical and thermal loads. Distribution of mechanical property of material is considered along the shell stick through the power distribution function. Thermal loads have been taken to signify the difference of temperature between outer an...

In this study, the residual strain was evaluated for human saphenous vein. Rings of the vein from four donors (two male and two female; age 62±5 years) were radially cut to obtain the opening angle (α) of the tissue. It was found that the average opening angle is 45°±18° (mean±SD). Then, the intraluminal distribution of circumferential stress was computed for one donor in order to verify the un...

In order to control residual stress distribution in glass, techniques based on the phenomenon of photoelasticity are efficient, though subject to the inherent limitations of all optical techniques. To mitigate these limitations, we exploit the phenomenon of acoustoelasticity to estimate residual stress distribution, using surface acoustic waves. In this study, we characterize the surface residu...

Abstact:The term “stressstrength reliability” when it appears in statistical literature typically refers to the quantityP(X > Y), where a system with random strength X is subjected to a random strength Y such that a system fails, if the stress exceeds the strength. Stress –Strength reliability is considered in this paper where the strength follows finite mixture of two parameter Lindley distrib...

The paper presents a complete analysis of the probabilistic structure for the von Mises stress. Von Mises stresses are a nonlinear function of the stress vector components, so the form of their probability distribution is not known a priori. The resulting probability distribution is not gaussian, nor it is centered about zero, even when the stress vector components are gaussian with zero mean. ...

Distribution of residual stresses arising after welding is quite complex and inhomogeneous. Many factors have influence on the magnitude and the profile of the stress distribution curve. In the present paper an x-ray technique was used to analyze the residual stress distribution in steel sheets jointed by industrial welding with linear or circular weld seams. Interpretation of experimental resu...
