Abstract:The ultimate strength assessment method of corroded plates based on corroded volume loss had been proposed by the theoretical derivation and Finite Element Analysis in the previous researches. The method still needs to be validated by experiments before it is applied in engineering. Firstly, the jigs were designed and made for being suitable for the present testing machine system and simulating the simply-supported boundary. Secondly, ultimate strength experiments of plates with no corrosion were carried out in order to validate the assumptions about the plates in Finite Element Analysis. Thirdly, the corrosion parameters of the corroded plates were measured and the corroded volume loss was calculated in order to validate the proposed calculation method of the corroded volume loss. Lastly, ultimate strength experiments of plates with corrosion were carried out in order to validate the assumptions about corrosion damage in Finite Element Analysis and the ultimate strength assessment method of corroded plates based on corroded volume loss.
