| Summary: | Заглавие с титульного экрана The Lamb wave technique for quantitative analysis of deformation and fracture processes of aluminum alloy specimens has been investigated. In order to study the evolution of propagation of ultrasonic elastic waves throughout static and fatigue mechanical tests the set of informative parameters has been calculated. There are two frequencies used: 60 kHz and 350 kHz. The informative parameters of registered signals are plotted versus elongation (for static test) and number of cycles (for fatigue test). The behavior and features of the obtained graphs have been analyzed and discussed in order to establish the relation between stress-strain (or fatigue) state of the specimens and changes of Lamb wave propagation through the gage length of the specimen. |
