Quantitative Techniques for Assessing Fatigue Damage After Failure
Abstract
A significant quantity of the fatigue life studies and a considerable number of fracture investigations have been carried out to measure changes associated with the damage process. However, there are cur-rently no set rules for the fractographical assessment of fatigue damage, and efforts are being made to find suitable techniques or alter current ones. Consequently, this study looks at two efficient post-failure techniques for identifying and quantifying damage. Fracture surface topography analysis, or FRASTA, has been used to solve a variety of failure problems. This quantified fractographic approach was first used in the early 1980s and has since been improved upon in tandem with developments in computing and measurement methods. To understand the behavior of a material under stress, especially in fatigue scenarios, the second methodology is known as the "entire fracture surface method" in mate-rial science. This method involves analyzing the entire surface of a fracture, or the broken surface pa-rameters. This approach aids in forecasting fatigue life and comprehending fatigue phenomena.
