Numeric Simulation of Time-Dependent Remodeling of Bone Around Loaded Oral Implants
Eser, Atilim; Tönük, Ergin; Akça, Kıvanç; Cehrelı, Murat Cavit (2009-07-01)
Purpose: The objective of this study was to investigate the time-dependent biomechanics of marginal bone around osseointegrated dental implants within physiologic loading conditions. Materials and Methods: The remodeling of marginal bone around a 4.1-mm-diameter, 10-mm-long implant was studied by implementing the Stanford theory into axisymmetric mathematical models simulating different bone support at the implant neck: 1-mm-thick cortical bone (model 1), 0.5-mm-thick cortical bone (model 2), absence of cor...
Analysis of stress distribution in a maxillary central incisor subjected to various post and core applications
Yaman, SD; Alacam, T; Yaman, Yavuz (1998-02-01)
In this study, stress distribution in a maxillary central incisor that was subjected to endodontic treatment and various post and core applications was determined by using a three-dimensional finite-element method. Cast gold post and gold core and different combinations of prefabricated stainless-steel post, or a prefabricated titanium post with amalgam or composite cores were considered. In all cases, the tooth was assumed to have a porcelain crown. The primary purpose of the study was to evaluate the stre...
Performance of polylactide against UV irradiation: Synergism of an organic UV absorber with micron and nano-sized TiO2
CAN, ULAŞ; Kaynak, Cevdet (SAGE Publications, 2020-08-01)
The main purpose of this study was to investigate mechanical and thermal performance of polylactide specimens against UV irradiation; first when only adding benzotriazole benzotriazole-based organic UV absorber (UVA), micro (200 nm) and nano (50 nm) sized titania (TiO2) particles alone, and then to reveal possible synergism when they are added together. Compounds were prepared by twin-screw extruder melt mixing, while the 2 mm thick specimens were shaped by compression molding. Specimens were exposed to UV ...
Hygrothermal fracture analysis of fibrous composites with variable fiber spacing using JK-integral
Saeidi, Farid; Dağ, Serkan; Department of Mechanical Engineering (2013)
In this study, a Jk-integral based computational method will be developed to conduct fracture analysis of fibrous composite laminates that possess variable fiber spacing. This study will be carried out for the fibrous composites exposed to not only thermal but also hygroscopic boundary condition, which results hygrothermal load. Formulation of the Jk-integral will be carried out by using the constitutive relations of plane orthotropic hygrothermoelasticity. One of the most important challenges of this study...
Shape optimization of wheeled excavator lower chassis
Özbayramoğlu, Erkal; Söylemez, Eres; Department of Mechanical Engineering (2008)
The aim of this study is to perform the shape optimization of the lower chassis of the wheeled excavator. A computer program is designed to generate parametric Finite Element Analysis (FEA) of the structure by using the commercial program, MSC. Marc-Mentat. The model parameters are generated in the Microsoft Excel platform and the analysis data is collected by the Python based computer codes. The previously developed software Smart Designer [5], which performs the shape optimization of an excavator boom by ...
