This work studied the performance effect and regeneration mechanism of organic–inorganic composite rejuvenator (COWRGO) composed waste cooking oil, rubber powder, modified graphene oxide on aged asphalt. The findings demonstrate that retained its storage stability for one year following restoration. rutting factor COWRGO regenerated asphalt was 43% higher than base at 64 °C. A reduction in stiffness 33% observed, accompanied by an increase m 15% a temperature −18 unrecoverable creep...
Axial stress monitoring in arbitrary cross sections is a challenging task. Stringers are the main axial load carrying components of aircraft skin structures and have typical complex sections. This paper investigates strategy an section based on acoustoelastic guided waves using piezoelectric lead zirconate titanate (PZT) sensors. To select appropriate wave frequencies modes sensitive for section, feature investigated theory combined with semianalytical finite element method. The mode shapes...

This study presents probabilistic-based damage identification technique for highlighting in metallic structures. utilizes distributed piezoelectric transducers to generate and monitor the ultrasonic Lamb wave with narrowband frequency. Diagnostic signals were used define scatter of different paths. The energy till times calculated by taking root mean square signals. For each pair parallel paths an error function based on is introduced. resultant then estimate probability presence monitoring...
