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 sensorsactuators. 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.
