Fatigue crack growth prediction method for offshore platform based on digital twin

Xin Fang et al.

Summary: This paper proposes a fatigue crack growth prediction method for offshore platforms based on digital twin, which establishes a digital twin model and utilizes a finite element surrogate model approach to ensure consistency between virtual and physical models. The method is validated through a crack growth experiment under mixed-mode multi-step loading, demonstrating reduced influence of uncertain factors and accurate crack growth prediction through dynamic tracking.

Structural fatigue life prediction considering model uncertainties through a novel digital twin-driven approach

Mengmeng Wang et al.

Summary: In this work, a digital twin-driven approach is proposed to accurately predict the fatigue life of a structure by establishing effective communication between a DT virtual model and a physical model. The proposed approach consists of three modules and operates in offline and online stages. Experimental results demonstrate that the proposed approach can efficiently and accurately predict fatigue crack growth.

Dual crack growth prognosis by using a mixture proposal particle filter and on-line crack monitoring

Jian Chen et al.

Summary: This paper proposes an online prognosis strategy for fatigue cracks by incorporating MPPF and SHM results, using a dynamic crack evolution model to handle multiple cracks, and integrating monitored crack sizes to construct effective importance probability density mixtures for new particle sampling. The effectiveness of the proposed method is demonstrated through leave-one-out validation on a dual crack growth problem in a hole-edge-cracked structure.

Honghui Wang et al.

Summary: This paper proposes an approach to predicting fatigue crack growth under mixed-mode loading based on an improved Gaussian process. By analyzing the theoretical background and implementing a local sample densification method, a fatigue crack growth prediction model using the improved Gaussian process is developed and verified to have better computational accuracy and efficiency than traditional methods.
