This paper presents a critical review of the main sensing techniques considered for online
monitoring of the integrity of alloys steel-made equipment used in process industry. This …

Most reported research for monitoring health of pipelines using ultrasonic guided waves
(GW) typically utilize bulky piezoelectric transducer rings and laboratory-grade ultrasonic …

Time of flight (TOF) is widely used to locate and size faults in ultrasonic non-destructive
evaluation (NDE). In this paper, we propose a novel model-based method for ultrasonic …

This paper proposes an effective method for corner-shaped components inspection using
ultrasonic phased array. We first improved the finite-difference time domain (FDTD) method …

Nondestructive detection and sizing of internal cracks initiated in reinforced concrete have
been critical problems. Geometric characterization of internal cracks and delaminations …

Grain size is a key parameter for polycrystalline material affecting the mechanical properties.
Ultrasonic attenuation method can be used to evaluate the grain size efficiently and …

In this paper, we propose a framework to automate the process of defect characterizing for
industrial structural component health monitoring by implementing automatic defect …

Pulsed eddy current testing (PECT) has the advantages of rich information, efficiency and
noncontact among defect nondestructive testing. Pulsed eddy current imaging technology …

Abstract Today, Phased Array Ultrasonic Testing (PAUT) is a suitable method for detecting
defects in Non-destructive Testing (NDT). This simulation was done with a new method on a …

Cracks, especially small cracks are difficult to be detected in oil and gas transportation
pipelines buried underground or covered with layers of material by using the traditional …
