A Stress Gradient Failure Theory for Textile Structural Composites MAY 2006 100 pages
Authors:  Ryan Karkkainen; Bhavani Sankar; FLORIDA UNIV GAINESVILLE MECHANICAL AND AEROSPACE ENGINEERING
The full text of this report is available for sale.Micromechanical methods for stiffness and strength prediction are presented, the results of which have led to an effective failure theory for prediction of strength. Methods to account for analysis of multi-layer textile composites are also developed. This allows simulation of a single representative volume element (RVE) to be applicable to a layup of an arbitrary number of layers, eliminating the need for further material characterization. Thus a practical tool for ...
