Considering the non-linear behavior of the viscoelastic material according to the change of environment,the GRNN is used tO make a model to predict the dynamic property of the material.

Design of extrusion die for plastic profiled bar based on 3D viscoelasticity penalty function finite element analysis;

Microstructure and viscoelasticity of mixed flour dough with tartary buckwheat and wheat;

Calculation of wrinkle recovery angles of fabrics using parameters of viscoelasticity solid models;

The pulse vibration with a certain frequence and amplitude was given to a metal deformation system,and the pulse vibration signal was transformed by Fourier method,one demension elasticity-plasticity constructive model and a visco-elasticity plasticity constructive model were built for vibration drawing.
