Abstract Scope |
This work collects scanning electron microscope (SEM) images of Ti-6Al-4V fatigue fracture surfaces and applies convolutional neural networks to build a dataset of fatigue fracture surface images and make a connection between them and fatigue life. Round bar specimens used in a previous study on fatigue life at various stress levels have been imaged in regular intervals with an SEM. The images capture the crack initiation site, short crack, and steady crack regions; multiple magnifications were utilized to determine which length scale allows the machine learning algorithms to infer physically meaningful information. The images are used to train CNNs from scratch and compared using unsupervised machine learning methods to determine if fracture surface alone can be linked to the fatigue lifetime. The images taken, the algorithms used, identified fatigue properties, and fracture characteristics will be presented. |
