Stress field analysis of functionally graded polar orthotropic disk on a rigid inclusion subjected to variable angular velocity Motameni, Ali; Farukoğlu, Ömer Can; KORKUT, İHSAN; Gürbüz, Rıza (2024-01-01) This paper analytically examines the stresses occurring on a functionally graded polar orthotropic variable thickness disk within the elastic region. The disk geometry is assembled on a solid rigid inclusion which is rotat...
Bioglass-polymer composite scaffolds for bone tissue regeneration: a review of current trends Motameni, Ali; ÇARDAKLI, İsmail Seçkin; Gürbüz, Rıza; Alshemary, Ammar Z.; Razavi, Mehdi; Farukoğlu, Ömer Can (2023-01-01) Biocompatible and bioactive composite scaffolds are essential in bone tissue regeneration because of their bioactivity and multilevel porous assemblies. There is a high demand for three-dimensional (3D) scaffolds to treat ...
Effect of compression precracking on near threshold region for AlSI 4340 steels considering compliance measurements Çalışkan, Salim; Gürbüz, Rıza (2023-01-01) Determining long crack threshold as a design criterion is not a new research topic; however, some anomalies because of different test methods in literature keep it voguish. Inaccurate estimations may result in considerable...
IN VITRO DEGRADATION AND BIOACTIVITY OF ANTIBACTERIAL CHROMIUM DOPED O-TRICALCIUM PHOSPHATE BIOCERAMICS Alshemary, Ammar Z.; Muhammed, Yasser; Salman, Nader A.; Hussain, Rafaqat; Motameni, Ali; Gürbüz, Rıza; Alkaabi, Mohammed Hliyil Hafiz; Abdolahi, Ahmad (2022-01-01) This study successfully incorporated different chromium ions (Cr3+) fractions into beta-tricalcium phosphate (beta TCP) using the wet-precipitation process aided by microwave radiation. The microstructure analysis of the p...
MESOPOROUS SULPHATE DOPED HYDROXYAPATITE NANOPARTICLES FOR CONTROLLED RELEASE OF PROTEINS ALSHEMARY, AMMAR Z.; Muhammed, Yasser; SALMAN, NADER A.; Motameni, Ali; Gürbüz, Rıza (2022-1-01) All rights reserved.The purpose of this study is to synthesize and characterize the mesoporous nanostructure of Hydroxyapatite (HA), evaluate the impact of the addition of sulphate ions (SO42-) on the microstructure proper...
Determining the endurance limit of AISI 4340 steels in terms of different statistical approaches Caliskan, Salim; Gürbüz, Rıza (2021-10-01) In engineering applications, fatigue phenomenon is a key issue and needs to be analyzed in the beginning of design phase in case of any component exposed to alternating loading on operation otherwise catastrophic fatigue f...
Effects of chromic acid anodizing on fatigue behavior of 7050 T7451 aluminum alloy Ilhan, Cagri; Gürbüz, Rıza (2021-09-01) The effect of chromic acid anodizing (CAA) surface treatment on 7050 T7451 aluminum alloy was presented in this study in terms of fatigue behavior. CAA is a treatment against corrosion by producing aluminum oxide layer (Al...
Biomechanical Evaluation of a Novel Apatite-Wollastonite Ceramic Cage Design for Lumbar Interbody Fusion: A Finite Element Model Study BOZKURT, CELAL; ŞENKÖYLÜ, ALPASLAN; Aktas, Erdem; SARIKAYA, BARAN; SİPAHİOĞLU, SERKAN; Gürbüz, Rıza; Timucin, Muharrem (2018-01-01) Objectives. Cage design and material properties play a crucial role in the long-term results, since interbody fusions using intervertebral cages have become one of the basic procedures in spinal surgery. Our aim is to desi...
Effect of Fillet Rolling Load on the Fatigue Performance of a Micro-Alloy Steel Diesel Engine Crankshaft Cevik, Gul; Gürbüz, Rıza (2017-01-01) Fillet rolling process is an effective method used to improve the fatigue performance of crankshafts by hardening the fillet region and inducing compressive residual stresses. This paper summarizes the work conducted to in...
