Stress distribution comparing

Photoelasticity images of pulsed laser ablation in water and in air were simulated by Finite Element Method. In the paper "Compare transient stress induced in in-air and in-water laser ablation using simulation method", the Von Mises stress distribution in the target is deduced from the simulated images and is compared between the two-ablation regimes. The result confirms that pulse laser ablation in the water can induced a stress about 100 times higher than that induced in ablation in the air.

Photoelasticity images of laser peening using sacrificial coating were simulated by the Finite Element Method. The Von Mises stress distribution in the coated target is deduced from the simulated images and is compared with the stress-induced in the non-coated target. In the paper "Study the stress enhancement effect of sacrifical coating in laser peening", the result shows that sacrificial coating can enhance the induced stress by a factor of 1.2.

Heat tolerance is a key parameter that affects insect distribution and abundance. Glyphodes pyloalis Walker (Lepidoptera: Pyralidae) is a devastating pest of mulberry in the main mulberry-growing regions and can cause tremendous losses to sericulture by directly feeding on mulberry leaves and transmitting viruses to Bombyx mori. Moreover, G. pyloalis shows a prominent capacity for adaptation to daily and seasonal temperature fluctuations and can survive several hours under high temperature.

Metal tolerance is often an integrative result of metal uptake and distribution, which are fine-tuned by a network of signaling cascades and metal transporters. Thus, with the goal of advancing the molecular understanding of such metal homeostatic mechanisms, comparative RNAseq-based transcriptome analysis was conducted to dissect differentially expressed genes (DEGs) in maize roots exposed to cadmium (Cd) stress.

The paper, finite elements analysis is performed using ANSYS Workbench software (version 18.2) on thin plates of bus with varying thickness and materials is of composite. The uniformly distributed and centralized load loading conditions are considered. The analysis result of deformation, stress and oscillation frequencies for different thicknesses. These results are compared analysis of the simulation accuracy.

This developed multiplicative formulation is considered to optimize the Austin-Moore model. The resulting model is called Optimized Austin-Moore (OAM). Considering several daily loading cases, the results show a more uniform stress distribution comparing with the classical solid stem. In addition, a significant increase of the stress levels around the metal/bone interface is obtained, that leads to favorable remodeling process.

Concrete is an inherently brittle material with a relatively low tensile strength compared to compressive strength. Reinforcement with randomly distributed short fibres presents an effective approach to the stabilization of the crack and improving the ductility and tensile strength of concrete. A variety of fibre types, including steel, synthetics, and natural fibres, have been applied to concrete. Polypropylene (PP) fibre reinforcement is considered to be an effective method for improving the shrinkage cracking characteristics, toughness, and impact resistance of concrete materials.

In writing this book the author has aimed first to present in readable form the main facts about the geographical environment of American history. Many important facts have been omitted or have been touched upon only lightly because they are generally familiar. On the other hand, special stress has been laid on certain broad phases of geography which are comparatively unfamiliar. One of these is the similarity of form between the Old World and the New, and between North and South America; another is the distribution of indigenous types of vegetation in North America; and a third is the...

The inverse relationship between coupon rate and price sensitivity results from the distribution of cash flows. Compared to a lower coupon bond, more of the total cash flow of a high coupon security will come from interest payments. Interest payments are received throughout the life of the bond, which means that, relative to a lower coupon bond, a higher coupon bond will have a higher proportion of its cash flow returned sooner. The earlier the cash flow occurs, the less price sensitive its cash flow is. As discussed above, longer maturity cash...

Descriptive statistics were used for demographic variables, expressed as mean and standard deviation in the case of continuous variables with a normal distribution. In case of an asymmetrical distribution the median and inter-quartile (IQ) values were used. Noncontiguous variables were presented as frequencies. The Shapiro-Wilk test was used to determine a normal distribution.
