An electromechanical model for the estimation of breakdown voltage in stretchable dielectric elastomer

Dielectric elastomer (DE) is capable of large deformation under electrical excitation. However, DE is susceptible to breakdown failure in this electromechanical actuation. Using an analogy of fracture mechanics, we establish an energetic model to estimate the breakdown voltage of DE in actuation. The non-linear characteristics, including material parameters, stretch ratios, and ambient temperature...
