Abstract

The combination of numerical simulations and experiments in dynamic material research P. Verleysen, J. Degrieck Faculty of Engineering, Department of Mechanical Construction and Production, Ghent University, Belgium Abstract In civil engineering structures quasi brittle materials, such as concrete and some composites, are often used. In most applications these materials are loaded dynamically. Consequently, the study of the dynamic behaviour of quasi brittle materials is of major importance. Based on a series of experiments, a material model to describe the dynamic tensile behaviour of quasi brittle materials was developed within the framework of damage mechanics. The constitutive equations describing the dynamic material behaviour have been implemented in a finite element program. The equations contain some material parameters. These material parameters are determined by means of a combined experimental-numerical tech- nique. The necessary experimental results are obtain
