Abstract

Modelisation of material damping of fibre reinforced microconcrete J. Vantomme, F. Habiyaremye Civil Engineering Department, Royal Military Academy, Belgium ABSTRACT The paper reports on the construction of theoretical models for the evaluation of material damping in microconcrete without reinforcement, and with reinforcement under the form of continuous steel fibres and randomly oriented steel fibres. The models are characterized by the energy balance approach which permits to express the global composite damping in function of three basic micromechanical damping mechanisms, associated with the stress-strain combinations of a plane stress state. This approach permits a fast evaluation of damping evolution with changing material parameters. INTRODUCTION A particular application of fibre reinforced concrete is found in the domain of protective construction, with the aim to resist explosive blast effects. Material damping capacity is generally neg
