Performance of short anchors inside the failure wedge
Demir, Berk; Pekcan, Onur; Department of Civil Engineering (2019)
The most widely accepted rule of thumb for anchor design is that bonded length of the ground anchors should be placed outside the failure wedge in order to increase resistance against overall stability. Moreover, failure wedge is defined as “no load zone.” This study investigates the performance of anchors inside and outside of the failure wedge by parametric studies performed through finite element analyses using Plaxis 2D and 3D. An anchored retaining wall with short and long anchors is compared with only...
Analysis of single phase fluid flow and heat transfer in slip flow regime by parallel implementation of Lattice Boltzmann method on GPUS
Çelik, Sıtkı Berat; Sert, Cüneyt; Çetin, Barbaros; Department of Mechanical Engineering (2012)
In this thesis work fluid flow and heat transfer in two-dimensional microchannels are studied numerically. A computer code based on Lattice Boltzmann Method (LBM) is developed for this purpose. The code is written using MATLAB and Jacket software and has the important feature of being able to run parallel on Graphics Processing Units (GPUs). The code is used to simulate flow and heat transfer inside micro and macro channels. Obtained velocity profiles and Nusselt numbers are compared with the Navier-Stokes ...
Numerical investigation of solidification
Alrmah, Masoud; Dursunkaya, Zafer; Department of Mechanical Engineering (2005)
Finite element solution of solidification process in 2-D Cartesian and axisymmetric geometries is investigated. The use of finite element may result in spurious increase of temperature in the field and the selection of the mushy zone range when used as a numerical tool along with the selection of the mesh size results in large errors in the predicted solidification time. The approach works best for problems where the mushy zone range is finite and the thermal conductivities of both phases are high.
Three-dimensional flow solutions for non-lifting flows using fast multipole boundary element method
Karban, Uğur; Uzol, Oğuz; Sezer Uzol, Nilay; Department of Aerospace Engineering (2012)
Driving aim of this study was to develop a solver which is accurate enough to be used in analysis and fast enough to be used in optimization purposes. As a first step, a three-dimensional potential flow solver is developed using Fast Multipole Boundary Element (FMBEM) for calculating the pressure distributions in non-lifting flows. It is a steady state solver which uses planar triangular unstructured mesh. After the geometry is introduced, the program creates a prescribed wake surface attached to the traili...
Buckling, postbuckling and progressive failure anaylses of composite laminated plates under compressive loading
Namdar, Ömer; Darendeliler, Haluk; Department of Mechanical Engineering (2012)
The aim of this thesis is to investigate buckling, post-buckling behaviors and failure characteristics of composite laminated plates under compressive loading with the help of finite element method and experiments. In the finite element analyses, eigen value extraction method is used to determine the critical buckling loads and nonlinear Riks and Newton-Raphson methods are employed to obtain post-buckling behaviors and failure loads. The effects of geometric imperfection amplitude on buckling and post-buckl...
