Full TextAbstract
Abstract The aim of this paper is the static analysis of functionally graded nanoplates by using the isogeometric analysis (IGA) approach and nonlocal elasticity theory. To consider small scale effects for nanoscale structures, the nonlocal elasticity theory is used. The refined plate theory which is suitable for both thin and thick plates, uses only four independent unknowns and satisfies the free transverse shear stress conditions on the top and bottom surfaces of plate and so a shear correction factor is not needed. The displacement field of model is derived based on physical neutral surface position. The IGA approach can easily formulate C 1 continuous elements by using Non-Uniform Rational B-Spline (NURBS) functions. Finally, numerical results are compared with other available solutions.
