This work discusses common practices and realistic considerations for piezoelectricity experimentation, modeling and simulation. It starts with highlighting some experimental considerations regarding the initial poling directions when bonding co-localized piezoceramic patches and their electric connections (or wiring) in order to have non nil current or voltage output. Next, the most used practical (engineering) modeling approaches, such as the thermal analogy and the strain induced potential (or field) approaches are discussed. Focus is made on their limitations and possible new solutions. Then, key features are presented to reach realistic simulations of piezoelectric free-vibration analyses under open-circuit electric boundary conditions, electrodes equipotentiality and electromechanical updating. Finally some concluding remarks regarding commonly chosen validation or/and benchmark examples are given for better modeling practices.
