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.
