This paper investigates the distribution of principal strain by micro mechanical measurement of concrete axial strain in Reinforced Cement Concrete (RCC) moderate deep beams across its width and depths for various span-to-depth ratios. A complete shear deformational behavior along with load-deflection response, crack patterns and modes of failure were studied experimentally. Twelve beams were t...

A two-dimensional mathematical model of the thermoelastic state has been built for a circular plate containing curvilinear inclusion and crack, under action uniformly distributed temperature across entire piece-homogeneous plate. Using apparatus singular integral equations (SIEs), problem was reduced to system two first second kind on contours crack inclusion, respectively. Numerical solutions ...

In this paper, the application requirement of Residual Property Model based on decrescent exponential function is reduced to only one mechanical test data. For this, by using Creager and Paris's elastic stress field equation in front blunt elliptical hole, theoretical radius was chosen for tip curvative maximum load direction at ensured be equal fracture toughness. Thus, workload model making u...

the cracked brazilian disc (cbd) specimen is widely used in order to determine mode-i/ii and mixed-mode fracture toughness of a rock medium. in this study, the stress intensity factor (sif) on the crack-tip in this specimen is calculated for various geometrical crack conditions using the extended-finite element method (x-fem). this method is based upon the finite element method (fem). in this m...

an elliptical tank cross-section is formulated to explore and optimization method, based on a real-coded genetic algorithm to enhance the roll stability limit of a tank vehicle. a shape genetic algorithm optimization problem is applied to minimize the overturning moment imposed on the vehicle due to c.g. height of the liquid load, and lateral acceleration and cargo load shift . the minimization...

In a previous work, a mechanism was presented by which baryon asymmetry can be generated during inflation from elliptically polarized gravitons. Nonetheless, the mechanism only generated a realistic baryon asymmetry under special circumstances which requires an enhancement of the lepton number from an unspecified GUT. In this note we provide a stringy embedding of this mechanism through the Gre...
