Technical Committee on Bond Models and their Applications for Numerical Analyses

The objective of the Committee was to understand bond behavior on a microscopic scale, and thus to review the information relating to bond behavior, and to make a proposal for using the information specifically through determination of a bond constitutive law which is practical in FEM. This paper reports the activities and describes part of the study results of individual working groups: Basic WG (to review and to introduce various topics relating to bond problems); WG2 (to study the FEM constitutive law; performing meso-scale FE analysis to determine τ-s relationship); and WG3 (FEM member WG; performing FE analysis of members’ experiments using several τ-s relationships).
