Numerical Simulation of Semi-Elliptical Axial Crack in Pipe Bend Using XFEM

In this work, XFEM is employed to obtain the stress intensity factors (SIFs) of a semi elliptical part through thickness axial crack. In XFEM, additional functions are employed to enrich the displacement approximation using partition of unity approach. Level set functions are approximated using higher order shape functions in the crack front elements to ensure the accurate modeling of the crack...

INVESTIGATION OF IMPACT RESPONSE OF Pb-FREE ASSEMBLIES AND COMPARISON OF DROP TEST WITH CYCLIC 4-POINT BEND

The popularity and miniaturization of handheld consumer electronic products such as cell phones, notebook computers, and PDAs has enhanced their probability of being subjected to shock loads; hence making impact reliability study an important area of research. The transition from tin-lead (Sn-Pb) to lead-free (Pb-free) solder has pressed the electronics industry to characterize formulate essent...

Numerical Investigation of Turbulent Mass Transfer in a 90° Bend

This paper presents a numerical study of local mass transfer coefficients in a 90° bend using the RNG version of k–e model to include the influence of curvature on the turbulent transport. Simulations were performed for flow through a 90°, 3-D bend for Reynolds numbers of 13500, 90000, and 390000, Schmidt numbers of 2.53 and 700 and curvature ratios of 1.5, 2, and 2.5. The differences betwe...

The numerical values of the nodal points for the Sturm-Liouville equation with one turning point

An inverse nodal problem has first been studied for the Sturm-Liouville equation with one turning point. The asymptotic representation of the corresponding eigenfunctions of the eigenvalues has been investigated and an asymptotic of the nodal points is obtained. For this problem, we give a reconstruction formula for the potential function. Furthermore, numerical examples have been established a...
