Abstract

Based on a continuum theory that accounts for the underlying molecular physics of polar elastomers (PEs), a typical boundary value problem (BVP) is developed to analyze the electromechanical instability (EMI) of PEs with randomly distributed dielectric particles. Through extensive numerical simulations, the effects of various parameters such as particle volume fraction, particle size, and enhancement factor related to polar groups on the critical voltage leading to EMI of PEs are investigated. The results are presented in 3D phase diagrams, which may better help researchers to understand EMI of PEs and guide them in synthesis, design, and application of PEs in the fields of chemistry, physics, bio-engineering, etc.
