ABSTRACT. THIS WORK PRESENTS THE TSAI-HILL THEORY TO CRACK PROPAGATION IN ANISOTROPIC MATERIALS APPLIED IN A BOUNDARY ELEMENTS SOFTWARE. THE OBJECTIVE OF THE SOFTWARE IS TO COMPUTE THE CRACK PROPAGATION DIRECTION AND THE INTENSITY OF STRESS ACTING AND RESULTANT STRAINS IN PLATES OF LAMINAR COMPOSITE MATERIALS. THE NUMERICAL RESULTS OBTAINED WERE COMPARED WITH RESULTS OBTAINED USING THE THEORY OF THE MINIMUM STRAIN ENERGY DENSITY TO CRACK PROPAGATION TO VALIDATE THEM.
KEYWORDS: DUAL BOUNDARY ELEMENTS METHODS, COMPOSITE MATERIALS, PREDICTIVE TECHNIQUES, ANISOTROPY
