Nonlinear dynamic response of piezoelectric sandwich beams resting on Winkler foundation

Key Points

• The dynamic response indicates significant sensitivity to variations in applied loads, and it varies across different configurations of beams.
• Analysis shows that the piezoelectric properties enhance energy harvesting capabilities of the beams under dynamic loads.
• Observational analysis focused on varying boundary conditions and interactions with the Winkler foundation—allowing insight into the beam's behavior.
• These findings support the potential for improved designs in structural applications, requiring further validation through real-world testing.
