In this study, we examined the bending behavior of S2-glass fiber reinforced polymeric materials with different crosshead displacement rates under out-of-plane loading condition. Out of plane loading condition is achieved with a three-point bending fixture. Three different crosshead displacement rates, 20 mm/min, 40 mm/min, and 60 mm/min, are chosen. Flexural strength, flexural modulus, and flexural strain at maximum load is analyzed. It is found that as the crosshead displacement rate increases from 20 mm/min to 40 mm/min, both flexural strength and flexural modulus shows an upward trend. However, when the crosshead displacement rate increases from 40 mm/min to 60 mm/min a drop in the flexural strength and modulus is observed.

Bu çalışma kapsamında, düzlem dışı yükleme koşulu altında farklı test hızları ile S2-cam elyaf takviyeli polimerik malzemelerin eğilme davranışlarını inceledik. Düzlem dışı yükleme koşulu üç noktalı eğilme fikstürüyle sağlandı. 20 mm/dk, 40 mm/dk ve 60 mm/dk olmak üzere üç farklı test hızı bu çalışmada kullanıldı. Maksimum yükte sehim miktarı, eğilme modülü ve eğilme mukavemeti test hızına bağlı olarak analiz edildi. Test hızı 20 mm/dk’dan 40 mm/dk'ya çıktıkça hem eğilme mukavemetinin hem de eğilme modülünün artış eğilimi gösterdiği bulundu. Bununla birlikte, yer değiştirme hızı 40 mm/dk'dan 60 mm/dk'ya yükseldiğinde eğilme mukavemetinde ve modülde bir düşüş gözlemlendi. CR - Amjadi, M., & Fatemi, A. (2020).
