Abstract

In order to evaluate fatigue properties within the very high cycle fatigue (>107 cycles) regime in a feasible timeframe, ultrasonic fatigue testing is necessary. This involves exciting specimens at their natural frequency of 20 kHz. As the fatigue performance of welds beyond the conventionally assumed fatigue limit has not been extensively studied, this research aims to investigate the fatigue behaviour of structural steel welds up to the gigacycle (109 cycles) regime. A welded specimen that features the toe and root features that fatigue cracks typically originate from was developed. The design process and fatigue results obtained will be discussed.
