Abstract
Bu çalışmada birden fazla çatlağı olan basit mesnetli elastik kirişte, hareketli yük altında çatlak ucundaki gerilme şiddeti faktörlerinin değişimi incelenmiştir. Çatlağın modellenmesi için kütlesiz dönel yay kullanılmıştır. Kirişin doğal frekansları ve mod şekilleri transfer matrisi metodu ile elde edilmiştir. Ardından, zorlanmış titreşim problemine ait hareket denklemi Newmark metoduyla sayısal olarak çözülmüştür. Üç farklı hasar durumu göz önüne alınarak çeşitli yük hızları için kirişte meydana gelen en büyük yer değiştirmelerin çatlak uzunluğu ve yerine bağlı değişimleri incelenmiştir. Çatlak ucundaki gerilme şiddeti faktörlerinin hareketli yükün hızına, çatlağın uzunluğuna ve yerine bağlı olarak değişimi detaylı olarak irdelenmiştir.
