摘要：

This paper represents fatigue crack growth life prediction in thin-walled structures (plates or shells). There are two analysis results from two different packages of software: NASGRO and FRANC 3D. They are based on Finite Element Method and Linear Elastic Fracture Mechanics principles (LEMF). Moreover, load interaction to crack growth is analyzed. FRANC 3D software is used to compute and display stress-displacement state of structure and simulation of crack fronts progression. Entire work comprises structural integrity assessment.
