Damage Models and Computational Tools for Health-Monitoring of Smart Structures

Abstract

The primary goal of this research was to develop physically based damage models, computational approaches based on shear deformation plate theories and layerwise theory, a finite element formulation for the analysis of thin and thick laminated composite structures with embedded sensors/actuators. During the period of this project the following tasks have been completed: (1) literature search to assess damage and failures models; (2) theoretical formulation of the layerwise models for smart composite structures, (3) formulation of damage models, (4) finite element analysis of laminated adaptive plate structures using the layerwise theory, and (S) finite element analysis of laminated adaptive plate structures Using the single-layer theories (classical, first-order and third-order plate theories). Geometric nonlinearities are accounted for and parametric effects of lamination schemes, material properties, and boundary conditions were investigated.
