A MATLAB toolbox for finite element analysis of structures

Kandemir, Volkan
In this study, an open source program for structural analysis was developed in MATLAB programming environment. Program was organized in object oriented manner by four new developed classes. Moreover, a graphical user interface for the end users was created. Furthermore, eight kinds of element including Plane Truss, Space Truss, Plane Frame, Space Frame, Linear Triangular, Bilinear Quadratic, Linear Tetrahedral and 3 Node Shell elements are ready to use. Elements were qualified by comparing the results obtained from the newly generated toolbox and commercial finite element analysis product named Abaqus and results were significantly consistent. Finally, Matlab codes are available in the attachment of thesis for further studies that will be done by other researches.


Automated 3D solid FEM generator of complex structures using laser scan data
Sharei, Maha O. M.; Türer, Ahmet; Department of Civil Engineering (2019)
For newly designed buildings, 3D modeling has become an integral part of analysis and design procedure using several simplified approaches by recognized and available software; in which user manually defines the geometry, loads, material properties, and support conditions of structures. Nevertheless, geometry modeling for historical complex structures, especially for masonry type construction, wall thicknesses, openings, section losses are difficult to be accurately defined in analysis programs. Changing wa...
A reformulation of the ant colony optimization algorithm for large scale structural optimization
Hasançebi, Oğuzhan; Saka, M.p. (2011-01-01)
This study intends to improve performance of ant colony optimization (ACO) method for structural optimization problems particularly with many design variables or when design variables are chosen from large discrete sets. The algorithm developed with ACO method employs the so-called pheromone scaling approach to overcome entrapment of the search in a poor local optimum and thus to recover efficiency of the method for large-scale optimization problems. Besides, a new formulation is proposed for the local upda...
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...
A Modified Parallel Learning Vector Quantization Algorithm for Real-Time Hardware Applications
Alkim, Erdem; AKLEYLEK, SEDAT; KILIÇ, ERDAL (2017-10-01)
In this study a modified learning vector quantization (LVQ) algorithm is proposed. For this purpose, relevance LVQ (RLVQ) algorithm is effciently combined with a reinforcement mechanism. In this mechanism, it is shown that the proposed algorithm is not affected constantly by both relevance-irrelevance input dimensions and the winning of the same neuron. Hardware design of the proposed scheme is also given to illustrate the performance of the algorithm. The proposed algorithm is compared to the corresponding...
An improved method for inference of piecewise linear systems by detecting jumps using derivative estimation
Selcuk, A. M.; Öktem, Hüseyin Avni (Elsevier BV, 2009-08-01)
Inference of dynamical systems using piecewise linear models is a promising active research area. Most of the investigations in this field have been stimulated by the research in functional genomics. In this article we study the inference problem in piecewise linear systems. We propose first identifying the state transitions by detecting the jumps of the derivative estimates, then finding the guard conditions of the state transitions (thresholds) from the values of the state variables at the state transitio...
