摘要: Abstract A meshless implementation of arbitrary 3D-shell structures based on a modified first order shear deformation theory (FSDT) is investigated in this paper. The FSDT improved manuscript to assume parabolic distribution the strain correct constant stress Mindlin–Reissner and get closer realistic through thickness. radial point interpolation method used construction shape functions arbitrarily distributed nodes general spatial shell geometry. convergence proposed model compared other well-known formulations found literature considering isotropic functionally graded structures. results obtained using demonstrate that very successful closed-form solutions finite element different theories. effect material deflections stresses also analyzed.
