Description
Summary:Laminated safety glass enables the safe construction of transparent structures. The mechanical behaviour depends on the polymeric interlayer both in the intact and in the post fracture state. In the present work, the mechanical behaviour of ethylene vinyl acetate-based (EVA) and ionoplastic interlayers is investigated for the intact laminated safety glass condition. In particular, the influence of the semi-crystalline structure on the stiffness behaviour is studied with X-Ray Diffraction, Differential Scanning Calorimetry and Dynamic-Mechanical-Thermal-Analysis. The studies on the mechanical behaviour of the interlayer in the fractured laminated safety glass were carried out with polyvinyl butyral-based (PVB) interlayers. First, the temperature and frequency (time) dependent linearity limits are determined in Dynamic-Mechanical-Thermal-Analyses, second, the nonlinear viscoelastic material behaviour is investigated with tensile relaxation tests at different temperatures and strain levels. Miriam Schuster, born in 1990 in Luxembourg, studied Civil Engineering from 2009 to 2014 at University of Luxembourg and TU Darmstadt. She focused and specialized on structural engineering. After working in the Luxembourgish engineering office Schroeder&Associés she returned to TU Darmstadt in February 2016 as a researcher in the Institute of Structural Mechanics and Design (ISM+D). In January 2022, she successfully defended her phd thesis with the topic “Characterization of laminated safety glass interlayers – Thermorheology, Crystallinity and Viscoelasticity”. Since then, she has been heading the glass and polymer unit of ISM+D as a postdoctoral researcher
