Modal analysis based on finite element method and experimental validation on carbon fibre composite drive shaft considering steel joints

Detecting Damage in Carbon Fibre Composites using Numerical Analysis and Vibration Measurements

“…Vibration analysis for cracked composite laminated plate and beam structures was developed by researchers (Ngo-Cong, Mai-Duy, et al 2011, Iliopoulos, Aggelis, et al 2015, El-Hafidi, Gning, et al 2017 who have concluded that damage is influenced by a structure's natural frequency, as the presence of damage decreases the natural frequency. Many investigators have also performed experimental and simulation studies to determine the frequency response function of carbon fibre composites and the dynamic damping behaviour of fabricated composites (Hu, Wang, et al 2006, Ding, Xie, et al 2015, Wang, Qin, et al 2017, Moustafa 2018. Free vibration analysis and modal tests of carbon fibre composite plates have been carried out by (Della andShu 2005, AbuShanab andMoustafa 2018) to measure the impact of buckling stress on the material's dynamic properties.…”

Effect of fretting wear on very high cycle bending fatigue behaviors of FV520B steel

“…The modal analysis of the specimens was applied using finite element analysis software ABAQUS [23,24]. For testing specimen of Test I, the resonance frequency of bending vibration mode is 19.827 kHz and the error is 0.865% compared with the standard frequency 7 0.01 mm, with a smaller elastic modulus by decreasing 4 orders of magnitude, was arranged at the contact surface between the clamps and specimen in order to simulate bending deformation of the testing specimen more accurately.…”

Sensitivity of the Viscous Damping Coefficient of Carbon Fiber in Carbon-Fiber-Reinforced Plastic with Respect to the Fiber Angle

“…The force signal can be achieved from an exciter or impact hammer, and the response data are usually measured by an accelerometer. The dynamics of CFRP structures were also identified via modal testing under the assumption of a linear system [12][13][14]. The measured modal Crystals 2021, 11, 781 2 of 14 damping coefficients showed a relatively large value compared with other lightweight materials [15,16].…”
