Aortic dissection refers to a serious condition where there is a tear in the wall of a major artery leading to blood flow within the layers of the aorta.
Abstract In this study, the high-strength pipe steel, i.e. X80, was heated at 260 °C for half an hour followed by air cooling for thermal simulation of pipe coating process. During the uniaxial loading of the specified tension samples, the migration behaviour of Lüders bands and the re-distribution of stress after strain ageing heat treatment were investigated using digital image correlation. Digital image correlation was adopted to characterise the local axial and shear strain fields of samples that were extracted from different locations across the wall thickness of the high-strength pipe...
