Background: The proposed research work aims not only to advance the understanding on the
effect of Environmentally Assisted Cracking (EAC) on the fracture resistance of the material, but preventing
catastrophic failure due to EAC as well.
Methods: The deterministic approach focuses on the understanding of the mechanics and mechanisms
of the fracture failure for EAC on a material level. The design of the crack stopper on the expected spots
of EAC is proposed and evaluated. Based on the submitted patent technology, an automatic lifting device
against uneven settlement of deep sea infrastructure is presented, using different reactions of two
enclosed and connected cylinders.
Results: The device could lift the settled structure for seconds, while surrounding earth could flow into
the lifted space due to hydrostatic pressure, resultantly the recovery of settlement and reduced stress
around crack tip automatically without using external electronic power and devices.
Conclusion: Therefore, it is expected that improved corrections for EAC, enhance safety maintenance
with accelerated decreasing life-cycle costs.
