As a typical nonlinear viscoelastic constitutive model, ZWT model[20,21,22], which is a parallel structure composed of a nonlinear spring and two Maxwell model, is suggested to describe PVB tension response:
Thus ZWT model with only one relaxation time, [[theta].
1] at 23[degrees]C are applied to fit ZWT model using universal global algorithm method and the corresponding results are given in Fig.
The above analysis is based on the experimental data at room temperature, while the ZWT model can be extended to various temperatures:
Four constitutive models considering rate effect based on ZWT model were proposed to describe mechanical behavior of PVB material under quasi-static tensile loading (in strain rate range 4 x [10.
This contract award reflects ZWT s strong reputation and execution track record within the Libyan market.
