Çatlaklı dairesel eğri kompozit kirişlerin titreşim analizleri

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.

Anahtar Kelimeler:

Eğri kompozit kiriş, çatlak, doğal frekans
