Paper Abstract

A high percentage of failures and damage propagation in materials and sensors employed in harsh industrial environments and airborne electronics is due to mechanical failure under tension and compression loads. Therefore, it is of paramount importance to test equipment reliability and ensure its survival in long missions in the presence of physical fluctuations. Mechanical testing systems (MTS) employ mechanical load in laboratories and all the scanning tests are performed after removing the sample from MTS machine. However, more precise tracking of failures and damages is possible only the moment the material is under loads. Hence, to systematically characterize and fully understand damage’s behavior, a system capable of Realtime scanning is required. The primary objective of this study is design, fabrication, and testing of a Realtime ultrasonic scanning using hydraulic arms (RUSH), which provides mechanical loads using hydraulic arms on the specimen and simultaneously scans it with ultrasonic scanning system. RUSH consists of two hydraulic pistons (for mechanical loading) and a main control unit that accurately calculates and sets the actuators’ input signals in order to generate desired load on the materials. In this paper, the system’s architecture, its mechanical structure, and electrical components are described. In addition, to verify RUSH’s performance, various experiments are carried out using unidirectional composites.
