Nonlinear Dynamic Response of Composite Rotor Blades

Abstract

Fundamental to the analysis of nonlinear dynamic response of composite rotor blades is the development of a continuum formulation that can accurately account for the effects of interlaminar shear and interlaminar normal stress variation thru-the-thickness of a laminate. Technical highlights of the research efforts to date are presented for each of the following proposed tasks: Nonlinear displacement formulation for composite media; Incorporate damage mechanisms into dynamic response formulations; and Correlation of formulated response model with experimental data. Keywords: Composite materials; Finite elements; Large displacement formulation; Assumed displacement; and Hybrid models.
