In this thesis, a panel finite element is developed for the analysis of the isotropic, open section, thin walled beams. In this study, the axial deformation, Euler-Bernoulli bending, Vlasov torsion and Kirchoff shell theories are combined to determine the displacements including in-plane and out-of-plane distortions in the cross sections of open section thin walled beams. The open section thin walled beam element is obtained by the assembly of panel elements. This element has two nodes each having 15 degrees of freedom. A MATLAB computer code is developed for the panel finite element anaysis to calculate the displacements and stresses at any point in the beam. The results obtained are compared to the results taken from literature and ANSYS software.

A hybrid stress element for thin-walled beams Oral, Süha (2003-04-05) A hybrid stress finite element for linear static analysis of thin-walled beams is presented. The element is based on Vlasov theory. The hybrid stress formulation is particularly suitable in this case where displacement assumption is not necessary and a simple polynomial assumption for independent stress resultants is sufficient to form the element stiffness matrix. The result is a simple and elegant element, which is accurate and cost effective. The formulation is assessed by analyzing a structure having op...
A Novel Numerical Technique for Analyzing Metasurfaces ÖZGÜN, ÖZLEM; Mittra, Raj; Kuzuoğlu, Mustafa (2019-12-31) This work presents a novel technique for efficient numerical modeling of electromagnetic scattering from metasurfaces comprising of truncated periodic or locally-varying quasi-periodic surfaces. The proposed technique hybridizes the periodic Finite Element Method (FEM) with the Method of Moments (MoM) to develop an algorithm far more efficient than conventional numerical methods for electromagnetic scattering from arbitrary objects. The key feature of the proposed algorithm is that it takes advantage of the...
A Beam Finite Element for Shear Critical RC Beams Filippou, Filip C; Sarıtaş, Afşin (2006-10-01) Over the past years techniques for non-linear analysis have been enhanced significantly via improved solution procedures, extended finite element techniques and increased robustness of constitutive models. Nevertheless, problems remain, especially for real world structures of softening materials like concrete. The softening gives negative stiffness and risk of bifurcations due to multiple cracks that compete to survive. Incremental-iterative techniques have difficulties in selecting and handling the local p...
A Numerical Model for Investigating the Effect of Rough Surface Parameters on Radar Cross Section Statistics Kuzuoğlu, Mustafa (2017-07-14) Electromagnetic scattering from rough surfaces is modeled by combining the periodic finite element method and the transformation electromagnetics approach. The behavior of the radar cross section (RCS) at both specular and backscattering directions is analyzed as a function of rms height and correlation length with the help of Monte Carlo simulations. The concept of backscattering enhancement is illustrated, and some conclusions are drawn about the RCS statistics.
A normalized set of force and permeance data for doubly-salient magnetic geometries Mahariq, İbrahim; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2009) In this study, a model is developed to represent doubly-salient magnetic circuits and to fit finite element analysis for the aim of obtaining a set of normalized normal force, tangential force, and permeance variation data. To obtain the desired data FE field solution method is used. The reliability of finite element results have been verified by three steps; first, comparing the numerical results with analytically calculated permeance, second, by solving two switch reluctance motors and comparing the resul...
