Material parameters for computer analysis of fibre reinforced concrete structures

[摘要] Methods and software tools for material parameter identification of high-performance cementitious composites are presented. The aim is to provide techniques for the purpose of advanced assessment of their fracture-mechanical properties and subsequent numerical simulations of components/structures made of these materials. The paper describes development of computational and material models utilized for efficient material parameter determination of studied composite. Such a determination is performed with the help of experimental data from four-point bending test used in inverse analysis based on artificial neural networks. It is a part of complex methodology for statistical and reliability analyses of fibre reinforced concrete structures.
