Upgrading of an Ultrasonic Fatigue Testing Machine by Means of Early Stage Damage Detection

Materials Testing, 2013
Abstract This contribution highlights the implementation of different methods for early stage damage detection in very high cycle fatigue (VHCF) experiments by means of an ultrasonic testing machine developed by BOKU in Vienna. Basically three different methods are used for in-situ evaluation of degradation: the analysis of (i) the ...

Fretting Fatigue Testing of Carburized Alloy Steel in Very High Cycle Regime Using an Ultrasonic Torsional Fatigue Testing Machine

Advanced Materials Research, 2014
Recently, high-strength alloy steels have been developed and used for various products. It is well known that fretting fatigue does not show fatigue limit. In other words, fretting fatigue failure may occur in very high cycle regime more than 107 cycles.

Machine learning modeling for ultrasonic quality attribute assessment of pharmaceutical tablets for continuous manufacturing and real-time release testing

International Journal of Pharmaceutics
In in-process quality monitoring for Continuous Manufacturing (CM) and Critical Quality Attributes (CQA) assessment for Real-time Release (RTR) testing, ultrasonic characterization is a critical technology for its direct, non-invasive, rapid, and cost-effective nature. In quality evaluation with ultrasound, relating a pharmaceutical tablet's ultrasonic
