Elastic analysis of orthotropic cylinders under different boundary conditions
Farukoğlu, Ömer Can; Eraslan, Ahmet Nedim; Department of Engineering Sciences (2016)
Analytical solutions are derived to examine the elastic responses of fixed end cylinders made of orthotropic materials. Cylinders are investigated under different boundary conditions which are internal pressure, external pressure, combined pressure and annular rotation respectively. Making use of Maxwell relations, orthotropic cylinders are transformed to isotropic ones. In order to exhibit numerical examples different orthotropic materials are used and compared. It is observed that orthotrophy slightly inf...
Elastic analysis of a circumferential crack in an isotropic curved beam using modified mapping-collocation method
Amireghbali, Aydın; Çöker, Demirkan; Department of Aerospace Engineering (2013)
The modified mapping-collocation (MMC) method is applied to analyze a circumferential crack in an isotropic curved beam. Based on the method a MATLAB code was developed to obtain the stress field. Incorporating the stress correlation technique, the opening and sliding fracture mode stress intensity factors (SIF)s of the crack for the beam under pure bending moment load case are calculated. The MMC method aims to solve two-dimensional problems of linear elastic fracture mechanics (LEFM) by combining the powe...
Elastic analysis of a circumferential crack in an isotropic curved beam using the modified mapping-collocation method
Amireghbali, Aydin; Çöker, Demirkan (2014-07-01)
The modified mapping-collocation (MMC) method was applied to the boundary value problem (BVP) of a circumferential crack in an isotropic elastic curved beam subjected to pure bending moment loading. The stress correlation technique is then used to determine opening and sliding mode stress intensity factor (SIF) values based on the computed stress field near the crack tip. The MMC method aims at solving two-dimensional BVP of linear elastic fracture mechanics (LEFM) circumventing the need for direct treatmen...
Elastic-plastic solutions of a long tube subjected to a temperature cycle
Kaya, Yasemin; Eraslan, Ahmet Nedim; Department of Engineering Sciences (2014)
In many engineering applications, cylindrical structures are often subjected to various temperature fluctuations. When the temperature gradient is high enough, the thermal stresses build up in the structure and these stresses may cause the permanent deformation of the body. Therefore, determination and detailed understanding of the thermoelastoplastic stresses in the cylindrical elements are an important issue of engineering design to predict the failures and improve the safety and reliability of the produc...
ELASTIC-PLASTIC STRESS ANALYSIS OF NONHOMOGENEOUS ROTATING SOLID DISCS
Eraslan, Ahmet Nedim; Gulgec, Mufit (2008-09-01)
A computational model is developed for the analysis of elastic and partially plastic stress states in functionally graded (FGM) variable thickness rotating solid disks. The modulus of elasticity, Poisson's ratio, uniaxial yield limit and density of the disk material are assumed to vary radially in any prescribed functional forms. Small deformations and a state of plane stress are presumed. Using the von Mises yield criterion, total deformation theory and a Swift-type nonlinear hardening law, a single nonlin...
