Abstract
AbstractA phenomenological material model is developed to understand the pseudo‐ductile material behavior of steel fiber reinforced high performance concrete (HPC) during failure. In that respect, an energy function is formulated using an additive composition of a transversal isotropic elasto‐plastic model and an elasto‐plastic phase‐field model representing the individual behavior of the steel fibers and the concrete material, respectively. Comparing the experimental data and numerical results of three‐point bending beam tests at low cycle for steel fiber reinforced HPCs, the efficiency of the presented model is verified.
