Infinite cylinder with a transverse crack and two rigid inclusions under axial tension Toygar, Meltem Evren; Geçit, M. Ruşen; Department of Engineering Sciences (1998)
Surface cracking in an orthotropic medium subjected to frictional contact Sarikaya, Duygu; Dağ, Serkan (2016-07-01) This article presents an analytical method capable of resolving the coupled problem of surface cracking in an orthotropic elastic medium subjected to frictional contact by a rigid flat punch. Reciprocal influences between the surface crack and the flat punch are accounted for by establishing a fully coupled formulation. Governing partial differential equations involving the displacement components are derived in accordance with plane theory of orthotropic elasticity. General solutions corresponding to mode ...
Numerical Design of Testing Functions for the Magnetic-Field Integral Equation Karaosmanoglu, Bariscan; Ergül, Özgür Salih (2016-04-15) We present a novel numerical approach to design testing functions for the magnetic-field integral equation (MFIE). Enforcing the compatibility of matrix equations derived from MFIE and the electric-field integral equation (EFIE) for the same problem, testing weights for MFIE are determined on given templates of testing functions. The resulting MFIE systems produce more accurate results that the conventional MFIE implementations, without increasing the number of iterations and processing time. The design pro...
Modified Combined Tangential Formulation for Stable and Accurate Analysis of Plasmonic Structures Karaosmanoglu, Bariscan; Ergül, Özgür Salih (2017-03-30) We present a modified combined tangential formulation (MCTF) for stable solutions of plasmonic problems involving metallic objects that are modeled as penetrable structures. For a wide range of negative real permittivity values, corresponding to the varying characteristics of the metals at infrared and visible frequencies, MCTF provides both accurate and efficient solutions in comparison to the conventional formulations. We explain the stability of MCTF in terms of the discretized operators for the limit ca...
Modified Combined Tangential Formulation for Stable and Accurate Analysis of Plasmonic Structures Karaosmanoglu, Bariscan; Ergül, Özgür Salih (2019-05-01) We consider a modified combined tangential formulation (MCTF) for stable and accurate analysis of plasmonic problems involving metallic objects modeled as penetrable bodies. For a wide range of negative real permittivity values, corresponding to varying characteristics of metals at THz, infrared, and visible frequencies, MCTF provides accurate solutions in comparison to the conventional formulations for penetrable objects. We further show that, for structures with subwavelength dimensions, penetrable models...
