This paper presents a multiscale approach for capturing the mechanical response of smart polymer materials. A spring-bead model is developed at the microscale based on results from molecular dynamics simulation to represent a bond cluster of polymer. Through parametric studies and mechanical equivalence optimization, a statistical network model is developed to represent the microstructure of the materials at the mesoscale. The introduction of the springbead based network model bridges the high accuracy molecular dynamics model at the microscale and the computationally efficient finite element model at the macroscale. A comparison between experimental and simulation results shows that the multiscale model is capable of capturing global mechanical response and local material properties.
