Manufacturing processes such as casting, rolling, forging, extrusion, material removal
processes, etc. are some of the common techniques used today in manufacturing industries …

Steel fibered high-strength concrete (SFHSC) became in the recent decades a very popular
material in structural engineering. High strength attracts designers and architects as it allows …

对材料和结构进行无损检测和评价在其全生命周期中非常重要. 超声检测是一种重要方法,

The field of NDT is a very broad, interdisciplinary field that plays a critical role in inspecting
that structural component and systems perform their function in a reliable fashion. Certain …

This study describes a useful contribution to the ultrasonic non-destructive evaluation of both
micro and macro-scale defects or damages induced in concrete under initial and peak level …

In this work, non-linear ultrasonic wave techniques have been used to detect the onset of
micro-cracking due to steel corrosion in model reinforced concrete elements. The specimens …

This study aims to develop combined methods with dual and triple use of different non-
destructive test (NDT) methods and to examine the effectiveness of these methods. For this …

Concrete-filled steel tubes (CFSTs) are structural elements that, as a consequence of an
incorrect elaboration, can exhibit internal defects that cannot be visualized, being usually air …

The aim of this work was to provide further confirmation of the possible use of non-linear
ultrasonic techniques for detecting the cracking due to corrosion of steel reinforcements in …

Nonlinear ultrasonic (NLU) and acoustic emission (AE) techniques are used for
nondestructive evaluation of concrete, damaged under compression loading. Experiments …
