Abstract

Abstract

In order to study the mechanical response of insulating laminated glass plates under single-curved cold bending, considering the effects of cold bending radius, glass plate thickness, insulating layer thickness and PVB interlayer thickness, circular arc single-curved cold bending tests were carried out on 12 designed insulating laminated glass plates. The stress distribution of the two tensile surfaces of the specimen and the variation characteristics of the relative slip values between the upper and the bottom glass plates were analyzed, and the effects of different designed factors on the test results were compared. The results showed that the maximum principal tensile stress of single-curved cold-bent insulating laminated glass plates was found at the midpoint of the long side of the outer convex surface, and the average difference of the maximum principal tensile stress between the two tensile surfaces was 15.5%; the interlaminar relative slip value increased nearly linearly with the increase of cold bending displacement; the principal tensile stress and interlaminar relative slip values were most affected by the cold bending radius. The maximum principal tensile stress increased by 101.5% and the interlaminar relative slip value increased by 54.0% as the cold bending radius decreased by 40%; with the increase of glass plate thickness or insulating layer thickness, the cold bending principal tensile stress and the interlaminar relative slip value would increase; the thickness of PVB interlayer had the least influence on the test results.
