- W4376648385 abstract "Irrespective of size and complexity, every civil infrastructure needs certain scrutiny regarding its structural health to ensure its serviceability during its lifetime. In olden times such scrutiny was done with the aid of destructive testing methods using sensors that required cumbersome and expensive installations and led to the destruction of at least part of the tested specimen. However, in recent times, many non-destructive methods, such as acoustic emission testing, electromagnetic testing, and laser testing methods have emerged, leaving the specified tested specimen undisturbed. With the advancement in sensor technology like motion magnification and with the help of access to high-speed cameras, a new method using a phase- based mechanism that is both cost-effective and nondestructive in nature becomes possible. This method will also aid in the measurement of structural dynamic responses of structures. The objective of this research was to perform a feasibility study on concrete blocks and fiber-reinforced polymer (FRP) cylindrical specimens to detect subsurface defects. In this method, test specimens are excited by external forces like a hammer, and their motion is analyzed using a high-speed camera and a phase-based motion magnification technique. This analysis gives information about any defects presented in the beneath layers of tested specimens. The obtained results signify the potential of the proposed technique in providing useful information for early warning of damage to prevent premature failure of the infrastructure." @default.
