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 …

Depending on material and details of cyclic loading conditions, fatigue damage develops
and spreads by various modes of crack initiation and subsequent crack growth. In order to …

The aim of this study was to identify the effects of aluminum content and strain rate on the
compressive strain hardening behavior of AZ31, AZ61 and AZ91D cast magnesium alloys …

A novel statistical approach to model size effects in very high cycle fatigue (VHCF) is
proposed in the paper. The statistical distributions of the VHCF life and of the size of the …

Ultrasonic fatigue tests (UFT) are used to study the fatigue life behavior of metallic
components undergoing a very high number of cycles (typically≥ 1 0 7− 1 0 9 cycles) under …

In the present investigation a full-surface view in situ thermography method is adapted to an
ultrasonic fatigue testing system. Full-surface view in situ thermography measurements were …

A fine granular area, FGA, is a typical phenomenon observed at the very high cycle fatigue
fracture crack origin with a subsurface defect in the material. The FGA has been widely …

This paper is concerned with an application of full-field calorimetric method for the
microplasticity evaluation in the very high cycle fatigue regime. The employed method is …

Detection and evaluation of micro-damages in the early stages of engineering failure are
crucial for various industrial structures to ensure their safety and prevent further catastrophic …
