Abstract

Bu çalışmada çatlaklı, çelik ve kompozit olmak üzere iki farklı malzemeden yapılmış olan dairesel eğri kirişlerin düzlem içi titreşimleri ANSYS’de sonlu elemanlar yöntemi kullanılarak hesaplanmıştır. İncelenen kiriş, Rayleigh-Ritz kirişi olarak ele alınıp kiriş üzerinde farklı konum ve derinlikteki çatlakların doğal frekanslarındaki değişim değerlendirilmiştir. Çalışma sırasında kiriş, konsol (Ank-Ser) ve iki ucu sabit (Ank-Ank) mesnetli bağlantı şekilleri ile tutturulmuştur. Farklı konumlarda ki çatlak ve çatlakların değişen derinliklerinde ilk üç moddaki doğal frekans değerlerinin beklendiği gibi değiştiği gözlemlenmiştir.

Keywords
