Abstract:

A TECHNICAL RESEARCH PROGRAM AIMED AT DEVELOPING AN ANALYTICAL PROCEDURE FOR INVESTIGATING THE DAMAGE PRODUCED IN COMPOSITE PLATES, DUE TO LOW VELOCITY IMPACT, IS PROPOSED. THE METHOD OUTLINED IN THIS PROPOSAL UTILIZES A HIGHER ORDER, SHEAR FLEXIBLE, PLATE BENDING FINITE ELEMENT. THIS ELEMENT INCORPORATES SHEAR DEFORMATION EFFECTS AND INCLUDES COUPLING BETWEEN MEMBRANE AND BENDING DEGREES OF FREEDOM. THE PROPOSED MODEL ALSO INCLUDES A NON-LINEAR CONTACT FORCE SPRING AND INDENTATION LAW FOR MODELING THE IMPACTOR AND CONTACT AREA. THIS MODEL WILL ALLOW COMPLETE GENERALITY IN DEFINING PLATE GEOMETRY, BOUNDARY CONDITIONS, MATERIAL PROPERTIES, LAMINATE CONFIGURATION AND IMPACTOR PARAMETERS.
