The aim of this study was to evaluate the stress and dislodgement resistance by finite element analysis of different types of fixation in mandibular orthognathic surgery. A 3D solid finite element model of a hemi-mandible was obtained. A bilateral sagittal split osteotomy was simulated and the distal segment was advanced 5 mm forward. After the adjustment and superimposing of segments, 9 differ...

The present paper is made up of two parts. In the first part, we study the mathematical stability and convergence of the quadrilateral MITC elements for the Reissner-Mindlin plate problem in an abstract setting. We generalize the Brezzi-Bathe-Fortin conditions to the quadrilateral MITC elements by weakening the second and fourth conditions. Under these conditions, we show the well-posedness of ...

This research finds a solution methodology for determining optimal travel path to and from existing facilities and corresponding location of a new facility having physical flow interaction between them in different degrees translated into associated weights, in presence of barriers impeding the shortest flow-path involving straight-line distance metric. The proposed methodology considers all ty...

This paper presents the excitation of a longitudinal slot on a hollow rectangular coaxial line by a metal support between two conductors and the fabrication by diffusion bonding of laminated metal thin plates. The measured loss of a straight line is 0.046dB/cm at 60GHz while the simulated one is 0.043dB/cm.

A thin film subject to in-plane compressive stress is susceptible to buckling-driven delamination. This paper analyzes a straight-sided delamination buckle with a focus on the effects of substrate compliance, following earlier work by B. Cotterell and Z. Chen. The critical buckling condition, the energy release rate and the mode mix of the interface delamination crack are calculated as a functi...

The DSSS radar is operational at our Institute using WiFi ‘b’ adapters and external horn at carrier frequency of 2.4 GHz. The system is able to detect a person, tree leaves, thin rod etc. The radar is tested using Flat plates of different cross sections and it results in a straight line curve will be very much useful in quantifying the target scattering parameters. Even this linear equation can...

We present a theoretical study of wave propagation in two adjoining floating plates of different flexural rigidity, such as fast-ice sheets that abut across a pressure ridge, etc. Analytical formulas for the transmission and reflection coefficients for various conditions at the interface are obtained using the Wiener-Hopf technique for the case of semiinfinite elastic plates joined by a straigh...

Single-loop elastic rings can be folded into multi-loop equilibrium configurations. In this paper, the stability of several such states which are either circular or straight investigated analytically and illustrated by experimental demonstrations. The analysis ascertains exploring variations energy for admissible deformations in vicinity state. approach employed is conventional conservative sys...

Abstract The focus of this study is to see if Friction Stir Processing can improve the properties an aluminium alloy with Boron Nitride (BN) particles on surface. (FSP) a new surface alteration technique that uses friction cause plastic deformation, resulting in grain refining and improved mechanical properties. To process 2024 plates, straight cylinder tool was used under varying parameters co...

The inverse finite element method (iFEM) is one of the best candidates to perform displacement monitoring (shape sensing) structures using a set on-board/embedded strain sensors. This study demonstrates high efficiency, robustness, and accuracy iFEM approach reconstruct geometrically non-linear deformations thin laminated plates shells by performing experimental measurements numerical analyses....
