摘要: Abstract A method to estimate material properties of viscoelastic materials is described for finite element (FEM) applications. Finite analysis performed on specimens with simple geometry find the relationships between ratio apparent Young's modulus modulus, Poisson's ratio, and shape factor. It suggested, basis results, that loss factor a be first derived from transmissibility measured specimen having small factor, subsequently obtained in such way FEM results force-deflection characteristics agree experimental large An example illustrated specific material.
