“…Compared with piezoelectric transducers, optical US detection has a much better performance in terms of sensitivity density and can be useful for high-resolution detection and applications [ 31 ]. Further, some optical US detection techniques enable noncontact remote sensing of US waves [ 10 , 19 , 31 , 35 , 36 , 48 ], which is particularly useful in certain NDT/E applications. A summary of the PA technologies used for NDT/E is provided in Table 1 .…”

“…Podymova et al [ 33 ] demonstrated the measurement of phase velocities, which can be utilized to determine the local porosity of SiC-particle-reinforced silumin-matrix composites. The local Young’s modulus of the composites can be determined by the pulsed PA method, and the effect of the porosity on the local Young’s modulus was quantitatively evaluated [ 36 ].…”

“…The lateral resolution is determined by the aperture of the transducer, which is on the order of millimeters. In this scheme, PA signal amplitudes and spectra, depth profiles, and B-mode images may provide useful information [27][28][29][30][31][32][33][34][35][36][37]. (2) PA computed tomography (PACT).…”

Photoacoustic (PA) imaging has been widely used in biomedical research and preclinical studies during the past two decades. It has also been explored for nondestructive testing and evaluation (NDT/E) and for industrial applications. This paper describes the basic principles of PA technology for NDT/E and its applications in recent years. PA technology for NDT/E includes the use of a modulated continuous-wave laser and a pulsed laser for PA wave excitation, PA-generated ultrasonic waves, and all-optical PA wave excitation and detection. PA technology for NDT/E has demonstrated broad applications, including the imaging of railway cracks and defects, the imaging of Li metal batteries, the measurements of the porosity and Young’s modulus, the detection of defects and damage in silicon wafers, and a visualization of underdrawings in paintings.

“…These properties can also be determined through both the traditional mechanical static methods such as tensile testing, four point bending and nanoindentation (N.B. Podymova, 2013) and dynamic methods such resonant ultrasound spectroscopy (Davide S. Paolino, 2017) and Impulse Excitation Test (IET). The IET technique, easy to perform and efficient, provide an attractive methodology to obtain the intended parameters.…”

3D Printing has recently undergone extensive development due to its lower cost and flexibility. A number of studies have been carried out to determine 3D printed material properties. This study focuses on the determination of the dynamic properties for PLA. The PLA material is processed through the popular FDM method with three different build orientations. A vibration experiment is conducted to evaluate the first modal frequency and Young’s modulus. The results are then compared to the FEM modal analysis and finally the traditional tensile testing results. The anisotropy of the 3D printed components, mainly due to the density changes caused by voids and filament alignment, result in the variation of the Young’s modulus which is different than the homogenous bulk material. The calculated Young’s moduli values are very slightly higher than the tensile test results which is in conformance with the trend documented by earlier studies on similar printed materials using the same techniques
