Abstract

STRESS INTENSITY FACTORS (SIF) ARE DETERMINED FOR AN INCLINED AND / OR ECCENTRIC CRACK IN A FINITE ORTHOTROPIC LAMINA USING THE BOUNDARY COLLOCATION METHOD. THE STRESS FUNCTIONS ARE DEFINED SUCH THAT THEY SATISFY GOVERNING EQUATIONS IN THE DOMAIN, THE BOUNDARY CONDITION ON THE CRACK SURFACE AND ALSO THE SINGULARITY AT THE CRACK TIP. THE UNKNOWN COEFFICIENTS IN THE STRESS FUNCTIONS ARE DETERMINED SUCH THAT THE BOUNDARY CONDITION ON THE EDGES OF LAMINA IS SATISFIED. THE ANALYSIS IS ALSO BEING CARRIED OUT FOR ISOTROPIC MATERIAL USING FINITE ELEMENT ANALYSIS SOFTWARE ANSYS FOR COMPARISON OF RESULTS. ALSO, COMPARISON OF RESULTS WITH EXISTING SOLUTIONS IS FOUND IN GOOD AGREEMENT.
