Abstract

A FINITE ELEMENT MODEL FOR STRUCTURAL ANALYSIS OF MEDIA WITH EMBED-DED INCLUSIONS IS PRESENTED. THE “EMBEDDED ELEMENT CONCEPT” IS ADOPTED TO MODEL THE CONTACT INTERACTION OF TWO MEDIUM COMPO-NENTS ALONG THE CONTACT INTERFACE CONSIDERING A MIXED 3D-1D FORMU-LATION. THE MOHR-COULOMB INTERFACE MODEL IS EMPLOYED TO DEFINE THE BOND-STRESS AND BOND-SLIP RELATION AND STRAINS ASSOCIATED WITH BOND-SLIP ARE ASSUMED TO REMAIN INFINITESIMAL ALONG THE INTERFACE. NONLINEAR ANALYSIS IS PERFORMED WITH A COROTATIONAL KINEMATICS DESCRIPTION INTRODUCED IN THE CONTEXT OF EMBEDDED APPROACH. THE PROBLEM OF LOAD TRANSFER IN MOORING ANCHOR SYSTEMS WAS INVESTIGATED AND REASONABLE RESULTS WERE OBTAINED USING THE PRESENT MODEL.
