Geometrically nonlinear isogeometric analysis of laminated composite plates based on higher-order shear deformation theory

摘要: Abstract In this paper, we present an effectively numerical approach based on isogeometric analysis (IGA) and higher-order shear deformation theory (HSDT) for geometrically nonlinear of laminated composite plates. The HSDT allows us to approximate displacement field that ensures by itself the realistic strain energy part without correction factors (SCFs). IGA utilizing basis functions namely B-splines or non-uniform rational (NURBS) enables satisfy easily stringent continuity requirement model any additional variables. nonlinearity plates is formed in total Lagrange small assumptions. Numerous validations isotropic, orthotropic, cross-ply angle-ply are provided demonstrate effectiveness proposed method.
