在本论文中，轻质泡沫状膨胀玻璃将被认为是船舶结构中的碰撞吸收材料。颗粒最初不用于此应用目的，因此必须确定此负载情况下的材料性能。为此，将压缩机压缩在铝筒中，使其高度小于其初始高度的一半。基于该实验，在非线性有限元模拟中将膨胀玻璃建模为Mohr-Coulomb材料，并从实验数据中识别本构方程的参数。（© 2016 Wiley‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
In the present contribution lightweight granulate like expanded glass will be considered as crash absorbing material in ship constructions. The granules were originally not intended for this application purpose, therefore the material behaviour for this load case has to be determined. To this end, the granulate is compressed in an aluminium cylinder to less than half of its initial height. Based on this experiment, the expanded glass is modelled as Mohr‐Coulomb material within a nonlinear finite element simulation and the parameters of the constitutive equations are identified from the experimental data.
