A vast amount of research has been carried out towards the goal of quantifying changes
related to the fatigue damaging process in materials throughout the fatigue life. However, no …

This paper presents a comprehensive review of the current state of knowledge of second
harmonic generation (SHG) measurements, a subset of nonlinear ultrasonic nondestructive …

Ever since high-strength steels were found to fail below the traditional fatigue limit when
loaded with more than 10 8 cycles, the investigation of metals' and alloys' very high cycle …

The recently increased interest in very high cycle fatigue properties of materials has led to
extended use and further development of the ultrasonic fatigue testing technique …

Metallic cast components inevitably contain defects such as shrinkage cavities which are
inherent to the solidification process. Those defects are known to significantly alter the …

The influence of internal casting defects on the fatigue properties of A357-T6 alloy has been
studied. Specimens with artificial casting defects (∅ eq≈ 2 mm) placed at the surface or in …

Fatigue failure can still occur beyond 10 7 cycles, ie very-high-cycle fatigue (VHCF), in many
metallic materials, such as aluminium alloys and high-strength steels. For VHCF of high …

In advanced engineering alloys where inclusions and pores are minimized during
processing, the initiation of cracks due to cyclic loading shifts to intrinsic microstructural …

This work considers the characterization of linear PVC acoustic properties using a linear
ultrasonic measurement technique and the non-collinear ultrasonic wave mixing technique …

The knowledge and experience with the very high cycle fatigue (VHCF) behavior are limited
compared to the low cycle and high cycle fatigue behavior of fiber-reinforced composite …
