Lengthscale Issues in the Mechanical Behavior and Failure of Composite Structures

Abstract

This effort, part of a larger four-year NICOP research effort, focused on improving the effectiveness of the prediction of the overall behavior, particularly failure, of composite structures. A key lacking item is the ability to effectively utilize data and observations made at lengthscales associated with laboratory-sized specimens in predicting the actual behavior manifested in full-scale structures. The specific work accomplished in this effort establishes a basic methodology for characterizing the details of damage and failure so that these can be effectively utilized in such an overall approach, thereby dealing with issues of different lengthscales and different levels of structural complexity.
