MODELING AND SIMULATION FOR AN OPTIMIZED DESIGN OF A DYNAMIC BENDING TEST

Abstract : Performance prediction of fibre-reinforced concrete structures under impact is of major importance in a wide range of industrial applications. Therefore, the study of the dynamic behaviour of the material is necessary to quantify the dynamic mechanical properties of the material in terms of both mechanical response and fracture behaviour : dynamic fracture energy and tensile strength. This study aims to design a modified Hopkinson bar bending test with a series of numerical simulations prior to the actual test in order to select a feasible experiment configuration. Results of a dynamic bending experiment on a steel fibre-reinforced concrete specimen loaded up to failure are presented.
