This paper attempts to provide a fatigue life prediction method for SLM processed Ti-6Al-4 V parts using a combination of ML and high-resolution SR-μCT. Prior to fatigue testing, SR-μCT was used to characterize the porosity and LOF defects, including their population, size, location, and morphology. Hinge fatigue testing machine uses Windows screens for test program settings. The machine is easy to operate and all test data can be stored (For example: test conditions, torque-angle curves, life curves, inspection reports, etc.) Hinge fatigue testing is a process used to assess the strength and durability of a hinge over time by measuring its fatigue levels.

What is Fatigue Testing? 1. From Latin "Fatigare" meaning "to tire." 2. Engineering terminology: - damage and failure of materials under cyclic loads. 3. Fatigue testing is defined as the process of progressive localized permanent structural change occurring in a material subjected to conditions that produce fluctuating stresses and strains at some point or points and that may culminate in .Test Setup: Using grips or fixtures, specimens are mounted in a fatigue testing machine. The equipment also has load or displacement measurement sensors for monitoring. . Data Analysis: Data are analyzed to determine metrics such as fatigue life, strength, stress-life curves, and crack growth rates, using statistical methods as applicable. .Fatigue life is a term used in fatigue testing and refers to the deformation and failure behavior of materials under cyclic loading. A fatigue life test with constant amplitudes is referred to as S-N test, where the tolerable stress amplitude is determined using the corresponding number of cycles.. Cycle characteristic values Types of loading S-N curve Testing machines
