Abstract

Specimens of A537cLl offshore structural steel were tested under cyclic loading and saltwater spray conditions. After the test, photographs were taken of the specimen surfaces where many pits were distributed randomly and then analyzed by using the slit island approach to determine their fractal dimensions. The result reported here reveals that the irregularity of the surfaces with many pits can be described very well by the fractal approach. Moreover, the fractal dimensions Df of the specimen surfaces increased with the increase in the number of cycles and the decrease in the residual life of those specimens.
