“…The crack paths in the geometry were modeled using a modified Forman equation. Toudeshky et al [12] developed a finite element subroutine for predicting the crack expansion path after patch repair, and the results showed that the fatigue crack life of the repair model agrees well with the experimental results. The crack expansion path is influenced by the direction of the composite fiber alignment, while the effect of thickness on the path is almost negligible.…”

The crack repair and transformation of port machinery has gradually become a hot-spot research. In this paper, a numerical analysis of tensile performance of central cracked steel plates repaired with CFRP sheets was conducted. The effect of the reinforcement method, the radius of the hole, the length of the fatigue crack and the size of the patch on the repair effect of the steel structure was investigated. The effect of repair was measured by the stressstrain state, load-displacement curve, and stress intensity factor. The results showed that the residual strength of the steel structure was significantly improved after the repair of CFPR materials, and a more reasonable patch size was given. The obtained results provided important methodological and data support for guiding the repairing work.
