CAI (computer assistant instruction) software of polymer viscoelasticity was designed based on Matlab/ Simulink.The computer programs consisted of various functional modules according to the viscoelasticity priciple of polymer.Experimental data and simulation parameters may be input and modified by clicking the corresponding modules.The direct-viewing simulation results will be obtained from the output modules such as oscilloscope

digital display and XY recorder.This software can demonstrate and simulate the viscoelasticity behavior of polymer both in static and dynamic state

such as hysteresis effect

dynamic mechanical loss

Boltzmann superimposition of strain and free vibration decay curve.The software can be used not only for instruction demonstration in polymer physics course

but also for design and study of polymer materials.
