ABSTRACT
In this study, investigation of low temperature effects on deflection behavior of a cracked laminated glass circular plates is conducted both experimentally and numerically. For the circular plates with no crack and with a surface crack, effect of PVB thickness is examined under different loading and thermal conditions. Also, free vibration behavior of cracked laminated glass circular plates are also considered to understand the deflection behavior clearly.
Results show that (i) there are sharp rising values of major normal stress and deflection for both interlayer thicknesses of 0.38 and 0.76 mm in the range of −85 to −100°C, (ii) for a cracked plate with 1.52 mm interlayer thickness, decreasing temperature gives approximately linear variations for the stress and deflection up till temperature of −85°C, (iii) in the same way as strain energy, decreasing interlayer thickness decreases shear stress, (iv) crack effect on free vibration characteristics are clearly observed for all three interlayer thicknesses.
