Abstract
Bu çalışmada cam elyafı takviyeli poliüretan dış yüzlü
ve rijit köpük çekirdekli sandviç kiriş eğilme rijitliğinin konsol kiriş
titreşim testi ile belirlenmesi konusu üzerinde durulmuştur. İmal edilen
sandviç kiriş numuneleri üzerinde yapılan konsol kiriş titreşim deneylerinden
elde edilmiş eğilme rijitliği değerleri bir sonlu elemanlar modeli ile ve 3
nokta eğilme deneyi ile elde edilmiş olan değerler ile mukayeseli olarak sunulmuştur.
Elde edilen neticeler konsol kiriş titreşim deneyi ile kompozit sandviç kiriş
eğilme rijitliğinin 3 nokta yükleme deneyinden daha yüksek hassasiyetle belirlenebildiğini
göstermektedir.
