Öğe Strength and failure analysis of inverse Z joints bonded with Vinylester Atlac 580 and Flexo Tix adhesives(Springer, 2012-11) Adin, Hamit; Turgut, AydınIn this study, the tensile strength and failure loads of the inverse Z joints were analyzed both experimentally and numerically by using two adhesives with different properties under a tensile load. Vinylester Atlac 580 and Flexo Tix were used as adhesives and the joints were prepared with two different composite materials. Initially, the mechanical properties of the adhesives were specified using bulk specimens. Then, the stress analyses were performed using three-dimensional finite element method (3-D FEM) via Ansys (V.10.0.1). The experimental results were compared with the numerical results and they were found quite reasonable. According to the test results, it can be seen that when the adherend thickness is increased, the stress increases as well. The most appropriate value of the adherend thickness is identified as t = 5 mm. Furthermore, it was observed that the lowest failure load was obtained at t = 3 mm the thickness for each specimen.Öğe The influence of adherend width on tensile strength and failure load of Z joints bonded with adhesive(International Journal of Physical Sciences, 2012-07-19) Adin, Hamit; işcan, BahattinIn this study, the influence of the adherend width on the tensile strength and failure loads of Z joints were analyzed both experimentally and numerically. The Z joints were subjected to tensile load in the experiments. The stress analyses were executed using the finite element method (FEM). The FEM analyses were performed with Ansys (v.14.0.1). The FEM analyses were carried out to investigate the stress and strain distributions in the adhesive layer of the Z joints. Experimental results were also compared with numerical results, thus they were found quite reasonable. The results showed that the joint strength and failure loads increased when specimen width (b) was increased. Lowest failure load was also determined at the 10 mm width for each specimen. In order to increase the performance of the joint, 30 mm was found to be the most suitable value of widthÖğe The effects of width on the strength of adhesively bonded Z joints subjected to tensile loads(Taylor & Francis, 2012-11-15) Adin, HamitIn this study, the effect of the adherend width on the tensile strength and the failure load of Z joints was analyzed both experimentally and numerically using two adhesives with different properties. Atlac™ 580 and Flexsotix™ were used as adhesives, and adherends were prepared with two different composite materials. To identify the mechanical properties of the adhesives, the bulk specimen method was used. Then, the Z joints were prepared using the aforementioned adhesives. The Z joints were subjected to tensile loads in the experiments. The stress analyses were performed using a three-dimensional finite element method (3D FEM). The 3D FEM analyses were performed with ANSYS (10.0). The 3D FEM analyses were performed to investigate the stress distributions in the adhesive layers in the Z joints. The numerical results compared favorably with the experimental results, and were found to be quite reasonable. The results showed that the joint strength increased when the specimen width (b) was increased. To maximize the performance of the joint for either adhesive, b=15mm was found to be the most suitable value for the width.Öğe The effect of overlap length adhesive with bonded in Z type materials(Academic Journals, 2011-09-11) İşcan, Bahattin; Adin, Hamit; Aydın, TurgutThe usage of adhesives as connecting method is increasing rapidly in today world. Many of research, development and engineering have been made to find the most important parameters of adhesion. In this study, stress analysis of bonded Z type that connected with various adhesives has been investigated. The adhesive thickness and overlap non-angle was constant but overlap length and overlap angle were varied. This paper has deal with the effect of overlap length on predicting of failure load of adhesive. An effective method for numerical solution in finite element method (FEM) has been performed in analysis. The FEM code employed was ANSYS(10.0). Experimental results were compared with numerical results and were found quite reasonable.Öğe Investigation of the effect of different variables on strength of adhesive joints(WILEY, 2014-10-01) Adin, Hamit; Deniz, Mehmet EminIn this article, the tensile strength of different adhesive bonded joints under a tensile load was analyzed numerically. The effects of certain parameters, including the bonding length and bonding ratio, were investigated. For this reason, the epoxy adhesive was used. Joints were prepared with aluminum materials. The stress analyses were employed using the Finite Element Method (FEM). ANSYS (v.14.0.1) FEM tool was utilized to investigate the stress distribution characteristics of aluminum lap joint under tensile loading. Numerical results were found to be quite reasonable. The numerical results show that the influences of variations are very notable when the equivalent stresses are between 18 MPa and 20 MPa. © 2014 WILEY-VCH Verlag GmbH & Co.

Tensile tests were carried out using Scarf Lap Joints (SLJs). Commer-cially available epoxy (Atlac 580) was used as adhesive and fiber reinforced epoxy/glass (Hgw 2372Grade G10 EP GC 203) was used as adherends. The stress analyses were performed using a three-dimensional Finite Element Method (FEM). The FEM analyses were executed with Ansys (V.14.0.1).Experimental results were compared with the FEM results and found quite reasonable. The results haveindicated that when overlap angle increases, the failure load values also decrease in all joints.Öğe The effect of angle on the strain of scarf lap joints subjected to tensile loads(Elsevier, 2011-09-02) Adin, HamitIn this paper, the mechanical behavior of the scarf lap joints (SLJs) bonded with adhesive (Vinylester Atlac 580) under a tensile load was analyzed. The effects of scarf angle at the interface strain distributions of SLJs were examined. The stress analyses were performed via three dimensional Finite Element Method (3D-FEM). The 3D-FEM code employed was Ansys (12.0). Experimental results were compared with the 3D-FEM results and were found quite reasonable. The results indicated that the maximum values of the normalized epsilon(x) strain values were determined at 0 = 60 degrees in all joints.Öğe The investigation of effect of adherend thickness on scarf lap joints(Wiley-Blackwell, 2013-10) Adin, HamitIn this paper, the mechanical behavior of the Scarf Lap Joints (SLJs) bonded with adhesive under a tensile load was analyzed. The effects of adherend thickness at the interface stress-strain distributions of SLJs were examined. The stress-strain analyses were performed by Finite Element Method (3D-FEM). The 3D-FEM code was employed with Ansys (Ver.12.0.1). Experimental results were compared with the 3D-FEM results and were found quite reasonable. It was concluded that both experimental and 3D-FEM failure loads were increased with increased adherend thickness. The results indicated that the maximum failure loads were determined at t=8 mm in all joints. The analysis of the SLJs under tensile load showed that the stress and strain concentrations occurred around the edges of the joints.Öğe The effect of implant number and position on the stress behavior of mandibular implant retained overdentures: A three-dimensional finite element analysis(Elsevier, 2015-07-16) Topkaya, Tolga; Solmaz, Murat YavuzThe present study evaluated the effects of ball anchor abutment attached to implants with a 4.30 mm diameter and 11 mm insert length on stress distribution in a patient without any remaining teeth in the lower jaw. In the study, the stress analysis was performed for five different configurations (2 with 4 implant-supported and 3 with 2 implant-supported) and three different loading types using ANSYS Workbench software. The stresses measured in the 4 implant-supported models were lower compared to the stresses measured in the 2 implant-supported models. The stresses on the implants intensified on the cervical region of the implants. When the effects of the loading sites on the stress were examined, the loading on the first molar tooth produced the highest stresses on the implants.
