Year 2007, Volume: 2 Issue: 2, 241 - 252, 01.12.2007

Abstract

Özet: Rijit yarı-düzlem üzerine oturmuş öngerilmeli şerit plağın zorlanmış titreşim probleminin üç boyutlu doğrusallaştırılmış elastodinamik teorisi çerçevesinde matematik formülasyonu verilmiştir. Bu formülasyona karşılık gelen sınır-değer probleminin varyasyonel ifadesi oluşturulmuştur. Bu ifadede yer alan fonksiyonelin birinci varyasyonunun sıfıra eşitliğinden -virtüel iş prensibi esasında uygun denklem ve sınır koşullarının elde edilmesi ispat edilmiştir. Daha sonra bu koşullardan yararlanılarak şerit levhanın kapsadığı bölge sonlu elemanlara bölünerek problemin sonlu eleman ( SE ) modellemesi yapılmıştır.
Anahtar kelimeler. Elastodinamik denklemleri; Ön gerilme; Harmonik yük; Zorlanmış titreşim; Sonlu elemanlar yöntemi.
