LEARNING CONSTITUTIVE MODEL CONSIDERING FUZZINESS OF CHARACTERISTICS OF SOILS

Abstract

The empirical law is introduced considering fuzziness involved in the characteristics of soils. A model proposed in this paper is based on the viscoplastic model. The proposed model has the learning ability via the descent method and it enables the model to get preferable degree of accuracy and to be adaptable to some kinds of characteristics of compound soils. Three items are coordinated as a first step. Physical meanings of dynamics of the viscoplastic model, introduction of the empirical law with fuzzy inference rules, and the effective learning ability.
