Simulation of laminated glass loaded by air blast waves

Abstract
The calculation of laminated glass with finite element methods should consider the layered structure and the different material properties. A smeared and a layered finite element model are described, which can both be used to calculate the behaviour of laminated glass under fast dynamic loading. The layered model uses an elasto-plastic material law for the PVB interlayer. The high Young's modulus under high strain rates in comparison to the long-term value can be considered in this way. The results of both models are compared with experiments and show good correlation.
