Abstract: A methodology for predicting the non-linear static response and reliability of plates made of conventional composite and nanocomposite materials is presented. The methodology was developed by integrating micromechanics models for both conventional composites and nanocomposites with tools for strength and reliability analysis of plates. Inputs to the model for strength analysis are the material properties of the composite obtained from the micromechanics model and the plate geometry and boundary conditions. Output of the model for strength analysis includes the load-deflection data for a plate under axial or transverse loading. The reliability analysis approach yields the probabilities of the failure modes and the sensitivities of these probabilities to the random variables. The methodology is demonstrated on a rectangular plate subjected to an in-plane compressive load with initial imperfections.
