A 3D laser scan is utilised to derive surface morphology and corrosion pit depth distribution. This corrosion depth is analyzed with a probability model to assess the morphology difference and the characteristic of the corrosion pit depth at a particular volumetric change. Furthermore, the goodness fit test statistic is carried out to observe the propensity of corrosion depth to a specific distribution, i.e. the Gaussian and non-Gaussian. The corroded specimens that conform to Gaussian distribution are numerically modelled with ANSYS APDL to generate a Gaussian surface. Furthermore, the non-Gaussian surface model is simplified as a single corrosion pit with various geometrical shapes. The mesh convergence is carried out to provide accurate stress distribution. The procedure is adjustable and applicable to the other surface morphology.en1754-212X20234469484Taylor & FrancisProbability modelSurface morphologyPitting severityCorrosion pitsNumerical modellingMathematikTechnikIngenieurwissenschaftenJournal Article10.1080/17445302.2021.2021608Journal Article
