This book is intended for scientists and engineers who need to know about surface
roughness, how to measure and describe it and what practical problems it might cause …

This paper proposes a brief review of acoustic wave scattering models from rough surfaces.
This review is intended to provide an up-to-date survey of the analytical approximate or semi …

Ultrasonic thickness measurement (UTM) is regularly applied and important NDT (Non
destructive) method in structure and component integrity assessment. This method provides …

This paper introduces a methodology to recover the morphology of a complex rough surface
from ultrasonic pulse echo measurements with an array of equidistant sensors using the one …

The improvement of detection accuracy and reliability of micro delamination defect is
restricted by the rough surface. The flat bottom holes (FBHs) are frequently employed as …

The influence of surface roughness on the detection of subsurface scatterers using phase‐
coherent, ultrasonic immersion transducers is reported. Experiments were conducted with …

Spherical pressure vessels as fuel storage for space uses are usually made by the spinning
process and precise control of thickness is a prerequisite. The non-contact thickness …

Non-destructive evaluation (NDE) of cement hydration was conducted using pulsed and
continuous-wave terahertz systems. The transmitted and reflected terahertz (THz) waves …

In corrosion assessment, ultrasonic wall-thickness measurements are often presented in the
form of a color map. However, this gives little quantitative information on the distribution of …

Surface roughness of a sample has a great effect on the calculated grain size when
measurements are based on ultrasonic attenuation. Combining modified transmission and …
