Über das dynamisch-elastische Verhalten geschäumter Stoff
Different methods are described for determining the dynamic Young's and dynamic shear moduli of foamed plastics in the range 0.1 to 100 c/s — for harder substances up to 1000 c/s. In estimating the elastic modulus on short cylindrical probes with attached end surfaces the influence of the shape of the probe for given Poisson's ratio is considered theoretically and tested experimentally. The results obtained on a series of different materials can be explained in terms of a simple model for closed and open mesh foamed material.
