Crack three-dimensional review
WebNov 18, 2024 · Abstract. The Fitness-for-Service (FFS) approach requires the evaluation of the mutual impact of nonaligned, multiple cracks on each other. As such, initially one must resolve whether existing, nonaligned, parallel cracks in the structure should be treated as merged or as separate, multiple cracks for FFS evaluation. Criteria and standards found … WebJan 28, 2024 · In the finite element method, the numerical simulation of three-dimensional crack propagation is relatively rare, and it is often realized by commercial programs. In addition to the geometric complexity, the determination of the cracking direction constitutes a great challenge. In most cases, the local stress state provides the fundamental criterion …
