Abstract
The failure process in highly porous concrete was analyzed experimentally and
numerically. A triaxial visco-plastic damage model and a mesoscale representation of the
material composition were considered to reproduce static compression and drop weight
impact tests. In the mesoscopic model, concrete was considered as a four-phase material
incorporating aggregates, bulk cement paste, interfacial transition zones and meso-size air
pores. The stress-displacement relations obtained from static compression tests, the stress
values, and the corresponding damage levels provided by the drop weight impact tests were
used to compare numerical and experimental results. The objective is to analyze the
mechanical properties of a highly porous cementitious material numerically in accordance
with the exprimental results.
