Abstract
CURRENTLY USED ANISOTROPIC YIELD CRITERIA FOR UNIDIRECTIONAL FIBER REINFORCED COMPOSITES UNDER MULTIAXIAL STRESS STATES WILL BE CRITICALLY REVIEWED FOR MODELING ELASTROPLASTIC AND PSEUDO-PLASTIC RESPONSES OF METAL AND ORGANIX MATRIX COMPOSITES, RESPECTIVELY. USE OF MICROMECHANICS BASED MODELS WILL ALSO BE CONSIDERED. SOFTWARES FOR MODELING SUCH RESPONSE WILL BE PREPARED WITH AND WITHOUT THE EFFECTS OF INTERLAMINAR STRESSES AND WILL BE UTILIZED FOR NONLINEAR LAMINATE ANALYSIS AND PREDICTION OF FINAL FRACTURE. IN ADDITION, TWODIMENSIONAL FINITE ELEMENT ANALYSES NEAR MAJOR CRACKS OR OTHER STRUCTURAL DETAILS ARE PROPOSED FOR PREDICTION OF IN-PLANE OR INTERLAMINAR FRACTURE. FURTHER APPLICATIONS AND THREE-DIMENSIONAL FINITE ELEMENT ANALYSES ARE SUGGESTED IN THE FOLLOWING PHASES.
