Abstract: Heterogeneous porous materials, characterized by variations in porosity and pore distribution, exhibit complex mechanical behavior, particularly when subjected to fracture.Here, we present a numerical method using phase-field fracture technique in FEniCSX to study how changes in porosity and pore distribution impact the fracture behavior of cementitious materials.The results demonstrate that not only porosity but also pore morphology plays a significant role in fracture propagation and the overall response of cement-mortar.These findings highlight the importance of considering both the quantity and spatial arrangement of pores when assessing the mechanical performance and durability of cement-based materials.
