Mechanical vibration and shock. Characterization of the dynamic mechanical properties of visco-elastic materials - Poisson ratio based on comparison between measurements and finite element analysis Ingestion-build-68772 BS EN 12845 starts by1 Scope This part of ISO 18437 specifies two methods for estimating Poisson ratio or and elastic modulus for isotropic visco elastic or porous elastic materials for use in linear finite element method (FEM) computer programs or other numerical approaches to vibrational or acoustic problems in visco elastic structures of complicated geometry. The method is based on comparison between measurements of force deflection or stiffness characteristics for
