| Abstract: | Artificial neural network methods are applied totwo distinct aspects of material modelling in civil engineering.The first aspect is the constitutive behavior modelling and constituive model development for sand by means of BP algorithm.The second aspect is the improvement of constitutive model for sand through the adaptive method .The experiment shows that the neural network material model has truly learned the behavior of triaxial specimens of sand. |

| Keywords: | neural network triaxial constituive model adaptive method |
