In this contribution, the application of lattice models for the application of piezoelectric solids is investigated. Trusses are employed as lattice elements in order to model cohesion forces in the material. The regular triangular lattice with equal hexagonal unit cells is considered. In this work only the material without damage is analyzed as the first step in developing a suitable lattice model for predicting the failure behavior of the materials with strong electromechanical coupling. Appropriate techniques for defining the parameters of truss elements are derived and the influence of the parameters on the model performance is investigated. The efficiency of the proposed strategies will be demonstrated by suitable numerical example.
