Nowadays, it is possible to manufacture smart composite materials with embedded fiber optic sensors. These sensors can be exploited during the composites' operating life to identify occurring damages such as delaminations. For composite materials adopted in the aviation and wind energy sector, delaminations are most often caused by impacts with external objects. The detection, localization and ...

Abstract Purpose To establish a smart thin plate in which structural health monitoring (SHM) and active vibration control purposes are integrated, the locations of attached piezoelectric ceramic (PZT) actuators as well their applied normalized voltage investigated. Method Normal strains such coupled electro-mechanical systems defined using Kirchoff's classical laminate theory (CLPT), then, by R...

The paper deals with the modelling and analysis of thick piezoelectric multilayer composite shell continua applied to accurate and optimal design of adaptive (smart) structural components and systems in industrial applications. The smart composite is made of n laminae, in which each lamina can be used as either actuator, sensor, self-sensing actuator, or passive structural component. A discrete...

Abaqus/Standard simulation of Lamb waves in smart composite plates is investigated for detecting delamination type damage. Composite plates typical of aerospace structures are used and a PZT actuator is surface bonded to excite Lamb waves. Abaqus model of composite plate uses layered solid elements. Piezoelectric (PZT-5H) actuator is modeled using piezoelectric elements that have both displacem...

This thesis is concerned with an investigation of the control of responses of plate structures with piezoelectric layers and under complicated excitations modeled as a non-stationary random process. The plate structures and piezoelectric layers are both discretized by the mixed formulation finite element method (FEM). The investigation consists of three parts. The first part is a literature sur...
