Experimental and numerical simulations of stone blocks at the archeological site of Volubilis, Morocco

This study aims to compare the results obtained experimentally on a stone sample used in the construction of the Triumphal Arch of Caracalla in the archaeological site of Volubilis with those obtained numerically by two implemented models: the Concrete Model (CM) implemented in ANSYS software and the Concrete Damage Plasticity (CDP) model implemented in ABAQUS software. The objective is to determine the suitable model for accurately simulating the stones used in Roman heritage structures. Compression and tensile tests were carried out on cylindrical stone specimens. A comparison of the mechanical behavior of the stone was made between the experimental results and those from the two numerical models.
