Numerical calibration of elasto-plastic phase-field modeling of fracture for experimental pullout tests of single steel fibers embedded in high-performance concrete

摘要

In this contribution, a constitutive framework of elasto-plastic phase-field model of fracture is applied to simulation of pullout test of single steel fiber embedded in high-performance concrete and is compared to experimental results. For the description of the mechanical behavior the Drucker-Prager plasticity model is used. The aim is to examine the pullout behavior of a single steel fiber and its influence on the overall material behavior. Therefore, the mechanical behavior of high-performance concrete is studied in experiments. The predictive capability of the above mentioned model is analyzed in detail by simulating pullout tests and calibrated using experimental data.
