The current work presents an investigation on size-dependent nonlinear free vibration of porous skew and elliptical nanoplates. Formulations are based a four-variable higher-order shear deformation plate theory to satisfy automatically the traction-free condition, von Kármán geometric nonlinearity account for mid-plane stretching, Eringen's nonlocal elasticity capture scale effect. isogeometric analysis displacement control strategy employed synthetically obtain large amplitude responses New results show influences porosity distribution pattern, coefficient, parameter behaviors
