Application of Acoustic Emission and Vibration Diagnostics Methods in Compression Testing of Composite Specimens
The methodology of joint application of acoustic emission diagnostics (AED), vibration-based diagnostics (VBD), and videotaping for monitoring the load-bearing capacity of polymer composite material (PCM) specimens during compression tests is considered. Test specimens cut from a composite panel were divided into five groups of two specimens each. Before the compression test, the specimens of the second group were subjected to an impact with an energy of 50 J, the third group, with 70 J, the fourth group, with 90 J, and the fifth group, with 110 J. Assessment of the state of damage of the specimens during compression was carried out using AED, VBD, and video recording. The obtained results confirmed the high efficiency of the complex application of these methods. Their joint application allowed us not only to monitor the level of bearing capacity of the specimens in the loading mode, but also to trace the sequence of mechanisms of evolution of multilayer carbon fiber-reinforced plastic fracture in compression at the stage of ultimate deformation of the material.
期刊介绍：
Russian Journal of Nondestructive Testing, a translation of Defectoskopiya, is a publication of the Russian Academy of Sciences. This publication offers current Russian research on the theory and technology of nondestructive testing of materials and components. It describes laboratory and industrial investigations of devices and instrumentation and provides reviews of new equipment developed for series manufacture. Articles cover all physical methods of nondestructive testing, including magnetic and electrical; ultrasonic; X-ray and Y-ray; capillary; liquid (color luminescence), and radio (for materials of low conductivity).
