İki tabakalı kare kompozit plakların higro-termal yükler altındaki burkulma analizi Ritz yöntemi
kullanılarak klasik plak teorisi çerçevesinde incelenmiştir. Tabakaların farklı malzeme özelliklerine sahip
olduğu ve plak sınır koşullarının 4 tarafı basit mesnetli (SSSS) olarak alınmıştır. Plak burkulmasına ait
hareket denklemleri enerji ifadelerinden elde edilmiştir. Toplam potansiyel enerjinin minimum
prensibinden yararlanılarak Ritz yaklaşım fonksiyonları ile birlikte burkulma problemine ait
özdeğer/özvektör problemi çözülmüştür. Sayısal çalışmalarda, plak narinlik oranının, tabakalar arası
Young modülü oranının higrotermal burkulmaya olan etkileri araştırılmıştır.
