A One-dimensional Ubiquitiformal Constitutive Model for a Bi-material Rod

摘要

A one-dimensional linear elastic ubiquitiformal constitutive model for a bi-material rod under uniaxial tension is developed, in which, the explicit analytical expressions for both the effective elastic modulus and the displacement distribution are obtained. The calculated results of the effective elastic modulus for concrete are found to be in good agreement with previous experimental data.
