Viscoelastic materials are often used to add damping to metal structures, usually via the constrained layer damping method. The added damping depends strongly on material temperature and frequency, as do the underlying material properties of the visc

The method of additive properties was applied to the density and glass transition temperature, T g , of linear amorphous polyurethanes. This method assumes that certain polymer properties result from the additive effects of unique constituent group p
