This book consists of a collection of 27 articles dealing with the subject of probabilistic engineering mechanics with special emphasis on the ensuing computational issues. The book has two parts. The first part is meant as a tutorial on the basic aspects of probabilistic mechanics, whereas the second part is an overview of some of the applications that rely on probabilistic concepts for their ...

This section contains a review of physical fundamentals and results of practical implementation of methods of nondestructive testing (NDT) and evaluation. It also presents relevant information on magnetic, electrical, eddy current, HF electromagnetic, infrared, optical, acoustic, radiographic, penetrant and other (such as vibration, leakage testing and integrated) methods of NDT and evaluation ...

Phased array ultrasonic testing technology is of flexible, reliable, efficient and suitable for special equipment welds non-destructive testing. Sectorial scan angle range was investigated in this paper for phased array ultrasonic oblique incident pulse shear wave testing of special equipment welds made in low carbon steel. The theoretical calculation of ultrasound wave energy transmission coef...

Non-destructive testing using ultrasonic measurement is used to ensure the quality of the die-casting products. The quality of a casting depends on the presence of discontinuities such as porosity and on the final metallurgical structure. Discontinuities occurring in the sub-surface of the cast structure mostly have irregular surfaces which scatter the ultrasound waves and make ultrasonic testi...

The article is devoted to the issue of improving coordinate registration information in means automated non-destructive testing. Existing systems non-contact spatial position sensors testing are mostly focused on use signal fields different physical nature, for example, acoustic or optical, which created around these and amplitude methods processing. These do not provide necessary accuracy dete...

Glass fiber-reinforced polymer (GFRP) ship structures are generally fabricated by hand lay-up; thus, the environmental factors and worker proficiency influence fabrication process presence of error in non-destructive evaluation results. In this study, ultrasonic testing GFRP hull plate prototypes was conducted to investigate statistical significance influences design parameters, e.g., glass fib...

High-amplitude ultrasound (u0 > 100 nm) generated by pulsed laser material processing carries important information about the mechanisms of light-material interaction and the propagation of the wave within the work-piece. In addition, it can also be applied for the purpose of non-destructive evaluation of the sample. The propagation of high-amplitude ultrasonic waves inside a plate is measured ...

After different rolling conditions, four 7055 aluminum alloy samples with precipitation sizes were measured by scanning electron microscope, transmission microscope and laser ultrasonic. The attenuation coefficients of ultrasound ultrasonic calculated in the time domain, frequency domain wavelet denoising, respectively. relationship between precipitate size coefficient was established. results ...
