The high order shear deformation theory

This study introduces a novel Ritz approximation function to analyze the free vibrations of laminated composite shallow curved beams. The methodology utilizes polynomial functions-based Fibonacci series to develop the Ritz’s approximation function. The displacement field aligns with the high-order shear deformation theory designed explicitly for shallow curved beams.

We present a generalized three-variable high order shear deformation theory (THSDT) using isogeometric analysis (IGA) to analyze free vibration of functionally graded porous (FGP) plates reinforced by graphene platelets (GPLs) in this work. It is named as FGP-GPLs for a short. The proposed theory only has got three degrees of freedom (DOFs) per node as the same way of numerically solutions in three-dimensional (3D) solids.

The study results for dynamic response of PFGCP present the effect of geometrical ratio, elastic foundations: Winkler foundation and Paskternak foundation; loads: mechanical load and thermal load; and the material properties and distribution type of porosity. The results are shown numerically and are determined by using Galerkin methods and Fourth-order Runge-Kutta method.
