Abstract

THIS PAPER PRESENTS AN APPROACH TO A CONSTITUTIVE MODEL FOR ANISOTROPIC QUASI-BRITTLE MATERIALS, DEVELOPED IN THE FRAMEWORK OF RATE INDEPENDENT SOFTENING PLASTICITY, INVOLVING A YIELD CRITERION IN WHICH AN ANISOTROPIC FRICTION TENSOR IS INVOLVED. IT TURNS OUT TO BE USEFUL FOR MATERIALS CHARACTERIZED BY ULTIMATE BEHAVIOUR WHICH VARIES ACCORDING TO THE DIRECTION, SUCH AS COMPOSITE MATERIALS, ANISOTROPIC ROCKS, TEXTILES, MASONRY. A GEOMETRICAL REPRESENTATION OF THE LIMIT DOMAIN IN THE CASE OF PLANE STRESS, TOGETHER WITH THE RESULTS OF LABORATORY TESTS IS PRESENTED AND DISCUSSED.
