Simulation and Analysis of Crack Extension of Ship Structure Based on ABAQUS

The safety of ship structures has always been a focal point in the field of marine engineering, and the monitoring and assessment of crack propagation are crucial for preventing structural failure. With the rapid development of materials science and computer technology, simulation analysis has become an effective means of studying crack behavior. By applying advanced finite element software such as ABAQUS and combining it with the principles of fracture mechanics, accurate simulations of crack propagation can be achieved, revealing its development patterns. In recent years, the emergence of new methods such as Virtual Crack Closure Technique (VCCT), singularity element method, and cohesive zone models has provided new solutions for crack analysis in complex structures. These methods not only enhance the understanding of material behavior but also provide a theoretical basis for ship design, elevating safety to a new level. Overall, the simulation and analysis of crack propagation based on ABAQUS offer strong data support for the safety assessment of ship structures.
