In traditional textbooks, discussions generally focus on the region II scenario, where the Tresca criterion is seen as more conservative due to its smaller elastic region. Region IV, representing the theoretical possibility of von Mises’ criterion being more...

Following the general incremental theory of nonlinear electro-elasticity, we formulate the incremental governing and constitutive equations needed for vibration analysis and solve them numerically using the state-space method (SSM). The results demonstrate the influence of the applied...
