Abstract
AbstractStructural reliability analysis of piezoelectric ceramics needs the modeling of failure under coupled electro‐mechanical actions. Based on experimental results available in the literature, we suggest a non‐associative dissipative framework where the fracture phase field is driven by the mechanical part of the coupled electro‐mechanical driving force. Proposed degradation functions account for different electrical crack boundary conditions. The modeling capability of the framework is demonstrated by means of representative numerical examples.
