摘要
To describe the specific behavior of soft biological tissues that can be regarded as incompressible, a strain energy function for fiber-reinforcement materials based on two isotropic and anisotropic deformation invariants is developed and investigated. The anisotropic properties of simple composite materials were initially studied and now extensive hyperelastic modeling is used to analyze the dynamic characteristics of a dielectric elastomer membrane that experiences finite strains and is reinforced by one family of fiber. It should be noted that the presence of fibers in the rubber matrix will strengthen the structure, but here the presence of fibers will greatly reduce the electric field required to activate the dielectric elastomer and thus be stimulated with a lower voltage. It even helps to reduce the issue of instability that is a common thing in dielectric elastomers. Therefore, the effect of fiber angle orientation in an anisotropic dielectric elastomer under combined loads of biaxial tensile forces and an electric field with a focus on the damping effects is completely studied for different cases. Based on the Gent model, phase diagrams, dynamic response diagrams, and resonance frequency diagrams are also plotted for several values of fibers directions and damping coefficients.
