DEM simulation and electron microscopy analysis of the fatigue behavior of ultra-high performance concrete

摘要

This contribution deals with preliminary experimental and numerical results on the fatigue behavior of ultra-high performance concrete (UHPC). For this purpose, a set of experimental investigations has been performed on UHPC, pure aggregate and binder. To obtain structural changes, UHPC samples were examined using SEM and TEM. For numerical investigations of the mechanical behavior of UHPC, the bonded-particle model (BPM) has been used and calibrated with experimental data.
