Determination and evaluation of the interlaminar shear modulus of polyvinyl butyral using fibre optic sensors

Abstract The method of fibre optic strain measurement based on Rayleigh signal analysis enables the detection deformation behaviour laminated glass and modelling its load-bearing characteristics. system is already calibrated for surfaces by studies Chair Building Structure at Universität Siegen. In addition to discretely measuring systems, such as gauges, distributed particularly suitable determination interlaminar shear modulus. sensors used in bending tests supplement measurements taken with gauges inductive displacement sensors. study describes results modulus viscoelastic interlayers made polyvinyl butyral provides basis define evaluate a model finite element analysis.
