ABSTRACT In this study an elastomer wishbone bush was designed and developed to fulfil a specific durability test requirement. A number of design alternatives was analysed and developed using a finite element technique. During the design iterations it is aimed to reduce the maximum strain values and internal friction forces to enhance the durability performance [...]

Özet Çalışmada tek katmanlı kauçuk metal malzeme çiftinden imal edilmiş bir burca ön sıkıştırma işlemi uygulayarak radyal katılık değerlerindeki değişim ve ön sıkıştırmanın parça ömrüne etkisi incelenmiştir. Ön sıkıştırma işleminin sanal tasarım uygulamasında sonlu elemanlar analizi (SEA) kullanılmıştır. Analiz modelinin hazırlanmasında ve sonuçların değerlendirilmesinde MSC.Partan 2008 arayüzü, analizin yapılasında MSC.Marc 2008 r1 çözücüsü kullanılmıştır. SEA [...]

Abstract The dynamic mechanical behavior of rubber material has been investigated for the principle loading modes; tensile, compressive and shearing. For each loading mode, specimens were subjected to sinusoidal cyclic loadings at two different mean strain states and two different frequency values. Each specimen has experienced 100K cyclic sinusoidal loading under the corresponding mean strain [...]

ABSTRACT This study aims to investigate the most widely used hyper-elastic material models applied in finite element solutions of large deformation problems. Physical tests were carried out on specimens which are loaded under compression, simple shear and tension to obtain the stress-strain data for all loading modes, respectively. For the same physical tests, finite element [...]

Abstract Force-Displacement data of elastic and plastic regions were collected with tensile test of flat metal alloy specimen. After simplification of collected data, engineering and true stress-strain values of specified materials were obtained. The data, obtained in the tensile of flat specimens, were applied to the finite element model of specimen to perform a finite [...]
