Abstract It is important to avoid buckling during low-cycle fatigue testing. The load dependent on the specimen shape, material properties, and testing machine. In present investigation of hourglass-shaped specimens importance diameter radius curvature examined. Diameters 5 7 mm are examined with a ratio 4, 6, 8. machine used an Instron 8800 elongated rods for climate chamber. This leads reduce...

Abstract Rocket NG is a startup with experts in civil engineering, electronics, and network engineering. We offer operate self‐developed end‐to‐end IoT system for condition monitoring, assessment predictive maintenance. The reliable ease to apply. In this paper the autonomous monitoring discussed regarding security, reliability, of use artificial intelligence on edge (smart algorithms used node...

Abstract This work investigates the quasi-static, low-cycle and fatigue behavior of hybrid glass/ultra-high modulus carbon (GC) low modulus/ /high (CC) fiber composites. These pseudo-ductile unidirectional interlayer hybrids are a new type composites whose potential is not yet fully understood, particularly under cyclic/fatigue loading. Different test methods (digital image correlation, video e...

The purpose of this study was to compare the polymerization shrinkage stress of composite resins (microfilled, microhybrid and hybrid) photoactivated by quartz-tungsten halogen light (QTH) and light-emitting diode (LED). Glass rods (5.0 mm x 5.0 cm) were fabricated and had one of the surfaces air-abraded with aluminum oxide and coated with a layer of an adhesive system, which was photoactivated...

Detecting the mechanism of landslides and evaluating their dynamics is challenging, especially concerning composite landslides. For this purpose, several investigation monitoring techniques should be implemented to obtain reliable information on landslide characteristics (e.g., geological hydrogeological conditions type processes), kinematics (displacement rate), potential triggering mechanisms...

Wind turbine blade spar cap to shear web adhesively bonded connections can suffer from damage at the bond-line which propagate through structure compromising integrity. This study investigates changes in stiffness and damping of a thick adhesive joint test specimen during fatigue test. The is calculated using an extensometer determined vibration thermography. Fatigue tests showed three distinct...
