概要

• 論文の詳細を見る

• A model introduced in the present paper is capable of accounting for the cyclic behaviour of sand reasonably well. The salient features of the proposed model are summarized as follows : (i) Generalized forms of Cambridge models are given to yield function and plastic potential.(ii) A combination of isotropic and kinematic hardening is achieved.(iii) A non-associative flow rule is used.(iv) The isotropic hardening involves plastic work related to not only volumetric but also deviatoric deformation.(v) A translation rule of yield surface is specified by extending Ziegler's rule of kinematic hardening.(vi) The constitutive model is capable of describing contraction as well as expansion of yield surface with simultaneous translation.Several drained cyclic tests are simulated and good comparison with experimental results is reported.
