Ion-matrix sheaths related to targets with grooves

2002-05-01
Demokan, O
In this work, the ion-matrix sheath near a target with a rectangular groove is studied analytically. A two-dimensional model with a single groove is adopted. The potential and electric-field profiles within the groove are analyzed to provide insight regarding the uniformity and efficiency of ion implantation on its walls. The deviation of the sheath edge from the planar geometry is also illustrated. (C) 2002 American Institute of Physics.

Nonlinear Vibrations of a Beam with a Breathing Edge Crack
Batihan, Ali C.; Ciğeroğlu, Ender (2015-02-05)
In this paper, nonlinear transverse vibration analysis of a beam with a single edge crack is studied. In literature, edge cracks are generally modeled as open cracks, in which the beam is separated into two pieces at the crack location and these pieces are connected to each other with a rotational spring to represent the effect of crack. The open edge crack model is a widely used assumption; however, it does not consider the nonlinear behavior due to opening and closing of the crack region. In this paper, a...
Free-Vibration Analysis of Ring-Stiffened Branched Composite Shells of Revolution
Kayran, Altan (American Institute of Aeronautics and Astronautics (AIAA), 2010-4)
Application of the multisegment numerical integration technique is extended to the free-vibration analysis of macroscopically anisotropic filament-wound branched shells of revolution with ring stiffeners, considering the variation of the thickness and winding angle. The solution procedure is based on a modified-frequency trial method, which processes on the numerically integrated transformed fundamental shell equations that are obtained in terms of finite exponential Fourier transform of the fundamental she...
Ion-matrix sheaths related to planar targets with semicylindrical grooves
Demokan, O; Filiz, Y (AIP Publishing, 2003-01-01)
In this work, the ion-matrix sheaths near planar targets with infinitely long, semicylindrical grooves are studied analytically to optimize ion implantation, concerning a broad range of industrial products. The potential profiles inside and outside the groove are derived and the velocity components inside the groove are estimated. The variation of the angle of incidence on the surface of the groove and the constant potential contours outside the groove are obtained. Results are observed to be in good agreem...
Polyhedral linkages synthesized using Cardan Motion along radial axes
Kiper, Gökhan; Söylemez, Eres; Kişisel, Ali Ulaş Özgür (2007-06-05)
Polyhedral linkages using Cardan motion along radial axes are synthesized. The resulting single degree-of-freedom linkages are compared with some existing designs. The classification and the transformation characteristics of the linkages are given.
Active Vibration Suppression of a Smart Beam by Using an LQG Control Algorithm
Onat, Cem; Şahin, Melin; Yaman, Yavuz (2011-06-22)
The aim of this study was to design and experimentally apply a Linear Quadratic Gaussian (LQG) controller for the active vibration suppression of a smart beam. The smart beam was a cantilever aluminum beam with eight symmetrically located surface-bonded PZT (Lead-Zirconate-Titanate) patches which were utilized both as sensor or actuator depending on their location. A group of PZT patches closed to the root of the beam was used as actuators in the bimorph configuration and a single patch was nominated as a s...
