“…The thermal effect on the MSH annular plates was solved by Safarpour et al [14] using the generalized differential quadrature method (GDQM). In addition, the vibration characteristics and nonlinear frequency of the MSH disks and plates embedded in a viscoelastic media were investigated [15,16]. In all the studies mentioned so far, carbon fiber (CF) has been used mainly as the reinforcing component in macroscale.…”

In this paper, wave propagation in multi-scale hybrid glass fiber (GF)/carbon nanotube (CNT)/polymer nanocomposite plates is studied for the first time by means of refined higher-order plate theory. The hybrid nanocomposite consists of CNTs and glass fibers (GF) as reinforcing components distributed within a polymeric matrix. A hierarchical micromechanical approach is used to predict the effective mechanical properties of the hybrid nanocomposite, including the three-dimensional (3D) Mori-Tanaka method and the rule of mixture. Moreover, a refined-type higher-order shear deformation theory (HSDT) is implemented to take into account the influence of the shear deformation on the motion equations of the system. Then, the governing equations are achieved on the basis of the energy-based Hamilton’s principle. Finally, the derived equations will be solved analytically for the purpose of extracting the natural frequency of the continuous system. A set of numerical examples are provided to cover the effects of various parameters on the wave dispersion characteristics of the plate. It can be declared that the hybrid nanocomposite system can achieve higher wave frequencies compared with other types of composite structures. Additionally, it is found that the selection of the lay-ups and length-to-diameter ratio plays a significant role in the determination of the sandwich plate’s acoustic response.

“…The governing equations have been solved via GDQM. Nonlinear frequency and chaotic responses of the multi-scale hybrid nano-composite reinforced disk in the thermal and viscoelastic environments and a harmonic external load was investigated by Furjan et al 39,40 and the nonlinear governing equation was solved via GDQM. Chen et al 41 considered thermal buckling performance of multi-scale hybrid laminated nanocomposite disk subjected hygro-mechanical loading.…”

In functionally graded saturated poroelastic circular plates with immovable simply supported and clamped rims, the axisymmetric nonlinear bending under transverse thermo-mechanical loading has been parametrically studied and compared with the axisymmetric postbuckling and nonlinear bending under thermal loading. Based on the classical plate theory, Love–Kirchhoff hypotheses and Sander’s assumptions, the general coupled nonlinear radial and transverse equilibrium equations, central continuity, symmetry and boundary conditions has been derived in ordinary and state-spatial forms. The corresponding difference equations have been achieved by using the generalized differential quadrature method. The equations have been assembled and numerically solved by using the Newton–Raphson iterative algorithm. The effects of the mechanical and thermal loads, pore distribution type, porosity parameter, Skempton’s coefficient, and thickness and boundary condition type on the behavior of the deflection, whether caused by thermo-mechanical bending, thermal postbuckling, or thermal bending, have been investigated in detail. From the parametric study, a novel quantity determining bending behavior has been found. The axisymmetric themo-mechanical nonlinear bending deflection is inversely and nonlinearly proportional to thermal load when the quantity is greater than a critical value and is nonlinearly proportional to thermal load when the quantity is less than a critical value. It was verified that the plate behavior complies with the general rules known for FG saturated poroelastic circular plates and with those known for metal–ceramic functionally graded circular plates whose governing equations are mathematically analogous to those of the current research.

“…Al-Furjan et al. 25 also formulated displacement strain of nonlinear vibration of multiscale hybrid nano composite reinforced disk (MHCD) using third order shear deformation (TSD) theory and Von Karman nonlinearity. They found that chaotic motion and nonlinear function of the disk are not dependent on ratio of outer to inner radius.…”

Medical robots have massive potential for improving the precision and capabilities for doctors to perform surgical procedures. For detecting colon cancers, these robots are also capable of suturing and inchworm devices can move over the narrow passages as required inside human colon. Most of the existing medical robots are designed and developed in order to enhance their stiffness to minimize the vibration of the end-effectors to obtain good position accuracy. In addition to this, it is important to study the dynamic characteristics of the colonoscope, such as load, stress, and strain for understanding the suitability of material used for colonoscope. In this paper, silicone rubber with selected specifications is used as colonoscope material and Mooney Rivlin equations are solved using ABAQUS software. Pneumatic pressure is taken as input parameter (0.1 MPa to 0.5 MPa). Finite Element Simulation is carried out and results are plotted for various set of values of input pressure. The results obtained indicate that silicone rubber with specified characteristics is a suitable material for colonoscope and it increases the comfort for the patient by exerting less force on the colon while it is moved inside the colon.
