“…They investigated the effects of microstructure, elastic foundation, and the occupancy rate of microbeam on natural frequencies. Arani et al. (2015) studied the nonlinear vibration of smart composite microtubes and obtained the effects of the Knudsen number, nonlocal parameter, BNNT volume percent, temperature change, elastic medium, and aspect ratio on the nonlinear frequency and critical fluid velocity.…”

In this study, the divergence and flutter instability of a cantilever piezoelectric carbon nanotube (CNT) conveying flowing fluid is investigated by considering surface effects. The size-dependent governing differential equation of a piezoelectric CNT is derived using a Newtonian method based on the Eringen nonlocal elasticity theory and in conjunction with the Euler–Bernoulli beam model. The extended Galerkin method is employed to transform the partial differential equation into a set of ordinary differential equations. The resulting eigenvalue problem is solved numerically to determine the effect of nonlocal parameter, various values of piezoelectric voltage, and surface effects on the divergence and flutter instability of a CNT conveying a fluid. Results show that by increasing the voltage from negative values to positive values, the nondimensional critical velocity of the fluid flow decreases. In addition, it should be noted that the effects of the nonlocal parameter lead to a reduction of the flutter and divergence stability of the CNT. Finally, this research can be used to design fluid-conveying nanodevices based on piezoelectric CNTs.

“…Nonlinear buckling response of embedded piezoelectric cylindrical shell reinforced with BNNT under electrothermo-mechanical loadings using HDQM was presented by Mosallaie Barzoki [21]. Electro-thermo-mechanical nonlinear vibration and instability of a fluid-conveying smart composite microtube made of polyvinylidene fluoride (PVDF) were investigated by Ghorbanpour Arani et al [22] based on the modified couple stress theory and Timoshenko beam model.…”

Axially flowing and rotating fluid‐particle mixture‐induced vibration and instability of a sandwich cylindrical shell are the main contribution of this work. The sandwich structure is made from a functionally graded carbon nanotube‐reinforced composite (CNTRC) cylindrical shell integrated with piezoelectric sensor and actuator layers. In this regard, the perturbation velocity potential is introduced and the pressure exerted by a fluid is obtained by the linearized Bernoulli formula. The actuator layer is subjected to an applied voltage in thickness direction which operates in control of vibration and stability. Based on Mindlin shell theory, the motion equations are derived and solved by the differential quadrature method (DQM). A detailed parametric study is conducted to elucidate the influences of the vibrational modes, distribution type and volume fractions of single‐walled carbon nanotubes (SWCNTs), boundary conditions, volume percent of particles and applied voltage on the vibration and instability of the structure. Results indicate that the system becomes unstable in the form of flutter in the cases of angular rotation of the shell or fluid as well as axial flow and angular rotation of the fluid while in the case of the rotating shell containing a corotating fluid, the loss of stability does not occur.

“…It is supposed to help with the modelling of the laminate failure prediction, which is still under the consideration of science [ 37 , 38 ]. For laminates, the modelling methods used mainly in the case of brittle materials are adapted [ 39 ], but also those applied for nanomaterials [ 40 , 41 ], as well as behavior modelling by long-term [ 42 ] or cyclic [ 43 , 44 ] loads. In order to predict and model the above, it is necessary to understand the structure of the material in laminates; methods similar to those used for the classic materials are used [ 45 ].…”

The work aimed to assess the failure progress in a glass fiber-reinforced polymer laminate with a 3D-woven and (as a comparison) plain-woven reinforcement, during static bending, using acoustic emission signals. The innovative method of the separation of the signal coming from the fiber fracture and the one coming from the matrix fracture with the use of the acoustic event’s energy as a criterion was applied. The failure progress during static bending was alternatively analyzed by evaluation of the vibration signal. It gave a possibility to validate the results of the acoustic emission. Acoustic emission, as well as vibration signal analysis proved to be good and effective tools for the registration of failure effects in composite laminates. Vibration analysis is more complicated methodologically, yet it is more precise. The failure progress of the 3D laminate is “safer” and more beneficial than that of the plain-woven laminate. It exhibits less rapid load capacity drops and a higher fiber effort contribution at the moment of the main laminate failure.
