Acoustic emission (AE) is widely used for identifying source mechanisms and the
deformation stage of steel material. The effectiveness of this non-destructive monitoring …

This paper introduces a new acoustic emission (AE) characteristic to determine the
deformation stage of metals under quasi-static loading. The AE characteristic is extracted …

The application of gangue concrete can be an effective method to solve the massive gangue
heap and shortage of raw materials of concrete by replacing the gravel and river sand with …

In nonlinear ultrasonic testing, the quadratic and more recently cubic nonlinearity
parameters are frequently measured as a quantitative indicator of damaged material state …

In nonlinear ultrasound testing, the relative nonlinear parameter is conveniently measured
as a sensitive means of detecting and imaging overall variation of microstructures and …

Harmonic generation measurement is recognized as a promising tool for inspecting material
state or micro-damage and is an ongoing research topic. Second harmonic generation is …

In present work, consideration of small bending vibrations of an infinite screw dislocation in
a nondissipative medium is continued. It believed that braking of dislocation oscillations …

The present chapter discusses the parameter-based analysis of AE. This is particularly
useful in case full waveform recording is not available, or the acquisition rate is not sufficient …

The purpose of this research is to obtain the method of measuring the residual deformation
of plate with varying thickness (PWVT) based on nonlinear ultrasound (NLU) quantitatively …

Second harmonic generation (SHG), a laser-based surface technique, was used to
characterize near-surface defect evolution associated with mechanical deformation in 2024 …
