RECOVERABLE DEFORMATION OF COHESIONLESS SOILS

EXPERIMENTAL DATA SHOW THAT THE RECOVERABLE BEHAVIOR OF COHESIONLESS SOILS MAY BE FITTED CLOSELY USING CONSTITUTIVE RELATIONS CORRESPONDING TO A SPECIAL CASE OF THE FIRST ORDER THEORY OF HYPOELASTICITY. FOUR FORMS OF FIRST ORDER ISOTROPIC CONSTITUTIVE LAW ARE PRESENTED AND CONDITIONS ARE DETERMINED UNDER WHICH EACH LAW IS INTEGRABLE TO AN ELASTIC LAW. CONSTANTS FOR THE ISOTROPIC HYPOELASTIC LAW ARE THEN DETERMINED WHICH FIT AVAILABLE DATA FOR TRIAXIAL STATES OF STRESS AND IT IS SHOWN THAT THE RESULTING LAW IS INELASTIC. CONSIDERATION IS THEN GIVEN TO FITTING THE DATA BY AN ANISOTROPIC FIRST ORDER INCREMENTAL LAW. INTEGRABILITY CONDITIONS FOR TRIAXIAL LOADING STATES ARE OBTAINED AND SHOWN TO BE SATISFIED BY BOTH ISOTROPIC AND ANISOTROPIC LAWS. THE INTEGRATED LAW FOR TRIAXIAL LOADING FOR THE ISOTROPIC CASE IS OBTAINED AND DEMONSTRATED BY APPLICATION TO THE ANISOTROPIC CONSOLIDATION TEST. TESTS INVESTIGATING THE ELASTIC CHARACTER OF THE RECOVERABLE BEHAVIOR ARE DESCRIBED. /ASCE/
