Crack propagation in steel components presents significant challenges across critical engineering sectors including aerospace, automotive, and structural engineering. Component failures can lead to catastrophic damage, making accurate life prediction essential for safety and reliability.
Traditional experimental methods for studying crack growth are often prohibitively expensive and time-consuming. This is where advanced simulation techniques become invaluable. Our project demonstrates how the Extended Finite Element Method (XFEM) in Abaqus provides an efficient, accurate alternative for modeling crack growth in steel structures.

Advanced Crack Growth Simulation with XFEM in Abaqus
The Extended Finite Element Method (XFEM) represents a significant advancement in fracture mechanics simulation. This innovative approach enables cracks to propagate freely through finite elements without the computational overhead of traditional remeshing techniques.
