In this paper, stress-intensity factor solutions are presented for an embedded elliptical crack in a round bar subjected to tensile load. The factors (SIF) tabulated form and were obtained from three-dimensional finite-element analyses of configuration. provide the as function three dimensionless parameters representative size, aspect ratio flaw its relative position cross section. cover ranges...

This paper summarizes progress in the development of finite element methods for three-dimensional elastic-plastic stress analysis in fracture mechanics. The work is directed toward the study of stress states near flaws such as a part-through crack in a pressure vessel wall, and emphasis is placed on the large scale plastic yielding range The development of a computer program with large computin...

By considering that the distribution of measured light along any galactocentric radius of an elliptical galaxy can be well represented by a R Sérsic law, we propose in this paper a “discrete ordenate” method, which, for any value of n, allows an explicit expression for the luminous density, ρ(r), to be found that can be numerically evaluated to any required precision. Once we have this semi-ana...

This paper proposes a new approach for finding expressive and geometrically invariant parts for modeling 3D objects. The approach relies on identifying groups of local affine regions (image features having a characteristic appearance and elliptical shape) that remain approximately affinely rigid across a range of views of an object, and across multiple instances of the same object class. These ...

We have explored isotropically jammed states of semi-2D granular materials through cyclic compression. In each compression cycle, systems of either identical ellipses or bidisperse disks transition between jammed and unjammed states. We determine the evolution of the average pressure P and structure through consecutive jammed states. We observe a transition point ϕ_{m} above which P persists ov...

The paper presents UWB monopole antenna having Slotted orthogonal vertical semi elliptical sheets with finite ground plane. The simulated return loss, VSWR, input impedance and radiation pattern are discussed in this paper. The results show that the voltage standing wave ratio is less than 2 (VSWR< 2) and return loss (SS1111) is less than -10 dB along the operation bandwidth of 4.5 GHz to 13.8 ...
