Abstract

Laminated composite structures are now commonly adopted in mechanical applications requiring high stiffness-to-weight and strength-to-weight ratios. One of the main disadvantages of using laminated composite members is the difficulty of inspecting their critical-to-failure regions when undergoing critical loads. Piezoelectric materials as sensors and actuators have transformed conventional laminated composite structures into smart-intelligent ones. For instance, piezoelectric sensors can be used to assess the critical mechanical deformation while piezoelectric actuators can be used to induce the stiffness in laminated composite structures. Comprehensive analytical and numerical solutions for the mechanical failure and shape control analysis of smart laminated composite structures under complex loads still remain unavailable. This thesis presents a systematic development of novel analytical and numerical models for the mechanical failure and shape control of laminated composite structures integrated with piezoelectric sensors and actuators.
