A Multiobjective optimization toolbox development for parameter identification of elastomers
Tekin, Tanyel; Dal, Hüsnü; Department of Mechanical Engineering (2018)
Rubber materials are widely used in industry because of their hyperelastic behaviors. Rubber materials show a highly nonlinear behavior due to hyperelastic deformability. Thus, small strain theory can not be applied to rubber materials. Various hyperelastic models are proposed by different researchers by deriving stress-stretch relations. Those relations differ in various test conditions including uniaxial, equibiaxial, pure shear and biaxial deformation modes. In this thesis, ten hyperelastic models includ...
Design and modeling elastomeric vibration isolators using finite element method
Ardıç, Halil; Özgen, Gökhan Osman; Özkan, Sami Samet; Department of Mechanical Engineering (2013)
In this thesis, a process is developed for designing elastomeric vibration isolators in order to provide vibration isolation for sensitive equipment being used in ROKETSAN A.Ş.’s products. For this purpose, first of all, similar isolators are examined in the market. After that, appropriate elastomeric materials are selected and their temperature and frequency dependent dynamic properties are experimentally obtained. Parametric finite element model of the isolator is then constituted in ANSYS APDL using the ...
Generalized finitedifference method in elastodynamics using perfectly matched layer
Korkut, Fuat; Tokdemir, Turgut; Department of Engineering Sciences (2012)
This study deals with the use of the generalized finite difference method (GFDM) in perfectly matched layer (PML) analysis of the problems in wave mechanics, in particular, in elastodynamics. It is known that PML plays the role of an absorbing layer, for an unbounded domain, eliminating reflections of waves for all directions of incidence and frequencies. The study is initiated for purpose of detecting any possible advantages of using GFDM in PML analysis: GFDM is a meshless method suitable for any geometry...
Prediction of sound transmission characteristics of multiple elastomeric bulb seals
Barutçu, Burak Nebil; Çalışkan, Mehmet; Department of Mechanical Engineering (2017)
Prevention of transmitted sound through car doors is a critical issue; as doors are the weakest parts of a car assembly in terms of sound isolation performance. Main path for sound transmission is through the seals between the car body and the door. Hence, the examination of sound transmission loss characteristics of seals between the car body and door is important to improve the sound isolation characteristics of the door assembly. The aim of this research is prediction of the sound transmission characteri...
Prediction of sound transmisson through elastomeric bulb seals
Atamer, Serkan; Çalışkan, Mehmet; Özgen, Gökhan Osman; Department of Mechanical Engineering (2014)
September 2014, 111 pages Doors are the weakest parts of the buildings in terms of sound transmission. Examination of sound transmission loss characteristics of doors reveals two separate transmission paths to be considered, namely, transmission through door leaf and leak transmission through bulb seals. Seals are the important parts of the sound transmission loss characteristic of door structure owing to their weakness compared to door leaf. Hence, their insulation capability should be analyzed and optimiz...
