The influence of porosity distribution pattern on the nonlinear buckling and postbuckling behavior of porous cylindrical shells subjected to axial compression are investigated by the analytical approach in this paper. The material properties are assumed to vary through the thickness of the shell. There are three porosity distribution pattern types are considered.

his paper investigates the nonlinear vibration of imperfect smart sandwich plate which consists of an auxetic graphene reinforced metal matrix composite (GRRMC) core layer integrated with two magneto-electro-elastic face sheets. The Poisson’s ratio of the GRMMC core is negative while the material properties of magneto-electro-elastic face sheets depend on the volume fraction of piezoelectric and piezomagnetic phases.

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.

This paper presents a method for establishing the exact receptance function of a tapered axially functionally graded (AFG) beam with nonlinear ratios of properties using the Adomian method. In current papers, the Adomian method was applied for linearly tapered beams where the geometric series was used conveniently.

Ebook "Metal-organic frameworks for photonics applications" is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed.
