This project focused on Fracture Toughness (FT) and Fatigue Crack Growth (FCG) tests of Compact Tension (C(T)) specimens to be performed using Amsler Universal Testing Machine. This project’s main objective was to implement Crack Opening Displacement (COD) and compliance methods for crack measurements during FCG tests. This project used C(T) specimens for all tests. In order to setup this test, several accessories were fabricated, such as test specimens, clevis, integral knife edges, and gage beam. The test specimens, clevis, integral knife edges and gage beam fabrication were done at UTP’s Manufacturing Lab using conventional lathe and milling machines, electric discharge machining wire cut and other manufacturing tools and methods.
