A CLOSE-FORM SOLUTION TO SIMPLY SUPPORTED PIEZOELECTRIC BEAMS UNDER UNIFORM EXTERIOR PRESSURE

摘要

On the basis of two_dimensional constitutive relationships of piezoelectric materials, the analytic solution for simply supported piezoelectric beams under uniform exterior pressure was derived. Furthermore the results were also compared with the ones of FEM for piezoelectric materials. Thus the foundation for further research of piezoelectric materials’ distribution sensing mechanism and the validation of numerical methods such as FEM is provided.
