Abstract EN
Subsurface damage could affect the service life of structures.
In nuclear engineering, nondestructive evaluation and detection of the evaluation of the subsurface damage region are of great importance to ensure the safety of nuclear installations.
In this paper, we propose the use of circumferential horizontal shear (SH) waves to detect mechanical properties of subsurface regions of damage on cylindrical structures.
The regions of surface damage are considered to be functionally graded material (FGM) and the cylinder is considered to be a layered structure.
The Bessel functions and the power series technique are employed to solve the governing equations.
By analyzing the SH waves in the 12Cr-ODS ferritic steel cylinder, which is frequently applied in the nuclear installations, we discuss the relationship between the phase velocities of SH waves in the cylinder with subsurface layers of damage and the mechanical properties of the subsurface damaged regions.
The results show that the subsurface damage could lead to decrease of the SH waves’ phase velocity.
The gradient parameters, which represent the degree of subsurface damage, can be evaluated by the variation of the SH waves’ phase velocity.
Research results of this study can provide theoretical guidance in nondestructive evaluation for use in the analysis of the reliability and durability of nuclear installations.
