The nu erical results were co pared with the test data. The results show that the odel could si ulate the echanical properties of concrete aterial under uniaxial co pression uniaxial tension biaxial co pression andbiaxial tension conditions, , , and that the odel could reflect the failure envelope of concrete aterial under biaxial stress condition properly. The odel could predict the flexural and shear properties, aswell as the typical failure odes of concrete structures. However, the odel could not predict the echanical properties of concrete aterial under biaxial tension and co pression condition and the develop ent law of the volu etric strain of the, concrete.
