The accurate prediction of crack initiation and growth in heterogeneous engineering materials remains a central challenge in fracture mechanics. This study presents a comprehensive finite‑element framework for simulating fracture using COMSOL Multiphysics 6.1. A coupled / Phase‑Field approach is implemented, enabling the capture of both sharp crack fronts and diffuse crack zones without remeshing. Material heterogeneity is introduced through spatially varying elastic moduli and fracture toughness, reproducing realistic composite microstructures. Validation against analytical solutions (center‑cracked plate under tension) and experimental data (three‑point bending of a glass‑ceramic specimen) shows excellent agreement in critical load predictions (≤ 3 % error) and crack path morphology. Parametric studies reveal the dominant role of local toughness gradients on crack deflection and branching. The presented workflow—geometry creation, mesh refinement, physics coupling, and post‑processing—is fully reproducible and can be extended to multi‑physics problems such as thermo‑mechanical fracture or fluid‑filled cracks. The results demonstrate that COMSOL 6.1 is a powerful, flexible platform for high‑fidelity fracture simulations in complex engineering systems.
