The paper "Nonlinear vibration of functionally graded porous micro-beams resting on elastic foundation" presents the analysis of nonlinear vibration of functionally graded porous (FGP) micro-beams resting on an elastic foundation. The Euler-Bernoulli beam theory (EBT) and the nonlocal strain gradient theory (NSGT) are considered to establish the equations of motion of the micro-beam. The material properties of the micro-beam are assumed to be changed continuously along thickness direction according to simple power-law distribution.

Large deflections of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) sandwich beams are studied in this paper by a nonlinear finite element procedure. The core of the beams is homogeneous while the two faces are of CNTRC material. The effective properties of the two CNTRC face sheets are determined by an extended rule of mixture. CNTs are reinforced into matrix phase through uniform distribution (UD) or four different types of functionally graded (FG) distribution, named as FG-X, FG-A, FG-V, FG-O.
