Comparison between dog-bone and Gaussian specimens for size effect evaluation in gigacycle fatigue

Fracture and Structural Integrity, 2013
Gigacycle fatigue properties of materials are strongly affected by the specimen risk volume (volume of material subjected to a stress amplitude larger than the 90% of the maximum stress). Gigacycle fatigue tests, performed with ultrasonic fatigue testing

Analysis of Variables Affecting Reference Block Equivalency Process Using Ndt Ultrasonic Method

Engineering Proceedings
Non-destructive testing (NDT) aims to assess components without compromising their functionality by identifying internal defects. Ultrasonic testing, a key NDT method, uses sound waves (0.5–20 MHz) to detect imperfections and requires tool calibration ...
