Polymer materials have obvious viscoelastic properties. Viscoelastic mechanics mainly studies the relationship between deformation and external force, load time, load rate and other factors under the influence of external factors, as well as the stress field, strain field and relevant laws in the object. The deformation of viscoelastic materials is strongly dependent on time and temperature. The viscoelasticity of the material will change with the temperature. If there is no obvious creep at room temperature, there will be significant deformation and flow at higher temperature, and even the phenomenon of material failure will be different. If the temperature changes too much, it will change the mechanical properties of the material.
