Damage-Survivable and Damage-Tolerant Laminated Composites with Optimally Placed Piezoelectric Layers

Abstract

The main objective of the research is to assure that the embedded sensors/actuators in a smart laminated composite structure are damage-survivable and damage-tolerant. The research requires development of analytical and computational techniques and tools together with the experimental evaluation of smart composite structural elements. An understanding of electroelastic constitutive behavior is critical to predicting the response of a structure with embedded piezoelectric material. Our research efforts in this area has produced a concise formulation of linear constitutive relations that has been extended to the nonlinear case. The CDA (Composite Delamination Analysis) and SDACLP (Static and Dynamic Analysis for Composite Laminated Plates) packages have been modified to incorporate piezoelectric coupling in a quasi-3D and plane stress analysis.
