“…Thanks to Isogeometric analysis (IGA) [33], the mesh of NURBS elements can be built with higher-order continuity between two elements, the geometric model and analysis model are both approximated by using NURBS. Therefore, it can be a robust numerical method that deals with higher-order continuum theory in solving the mechanical responses of micro/nanostructures, and derived more accuracy results than classical finite element methods [34][35][36][37][38][39]. Fan et al [40] investigated the buckling and post-buckling responses of porous FG micro/nanoplates based on IGA and nonlocal strain gradient theory.…”

Co-curing double-layer damping films embedded composite structure has many advantages over a tradition composite, such as large damping, high specific strength etc. In order to study the dynamic performance of this composite clamped beams, a theoretical model of the free vibration of the beam was established by the combination of first-order shear deformation theory with the Hamilton principle and variational principle. The Galerkin method was presented to find the free vibration theoretical solution under the fixed-support boundary conditions. The theoretical solution was compared with the experimental results through the established experimental platform. According to the comparison results, the validity of the theoretical model was proved. Finally, the effects of the damping layer distribution and the geometric parameters on the dynamic performance were further explored. It provides a theoretical basis for the optimal configuration of double-layer damping films embedded composite clamped beams structure.

AbstractReinforcing polymers with nanofillers is an advanced approach to improve and manage the thermal behaviors of polymeric nanocomposite materials. Among the proposed nanofillers, graphene and carbon nanotube (CNT) with superior thermal conductivity are two advanced nanofillers, which have extensively been utilized to enhance the heat transfer responses of host polymeric materials. In this work, the impacts of randomly oriented graphene and CNT to steady state and transient heat transfer behaviors of functionally graded (FG) nanocomposite cylinders have been investigated using an axisymmetric model. Nanocomposite cylinders have been assumed to be under heat fluxes, heat convections or temperatures as different types of thermal boundary conditions. The thermal properties of the resulted nanocomposite materials are estimated by micromechanical model. Moreover, the governing thermal equations of axisymmetric cylinders have been analyzed using a highly consistent and reliable developed mesh-free method. This numerical method predicts temperature fields via MLS shape functions and imposes essential boundary conditions with transformation approach. The effects of nanofiller content and distribution as well as thermal boundary conditions on the heat transfer responses of nanocomposite cylinders are studied. The results indicated that the use of nanofiller resulted in shorter stationary times and higher temperature gradients in FG nanocomposite cylinders. Moreover, the use of graphene in nanocomposites had stronger impact on thermal response than CNT.
