Equivalent layered models for functionally graded plates
Functionally graded plates whose material properties vary continuously through the thickness are modelled as exactly equivalent plates composed of up to four isotropic layers. Separate models are derived for analysis using classical plate theory, firstorder and higher-order shear deformation theory. For cases where Poisson’s ratio varies through the thickness, the integrations required to obtai...
متن کاملRefined Shell Elements for the Analysis of Functionally Graded Structures
Functionally graded materials (FGMs), proposed in 1980s by the Japanese school of material science as thermal barrier materials [1], present a number of advantages that make them attractive in potential future applications, such a reduction of in-plane and transverse through-the-thickness stresses, an improved residual stress distribution, enhanced thermal properties, higher fracture toughness,...
متن کاملComparison study between layered and functionally graded composite beams for static deflection and stress analyses
The aim of this paper is to compare the static deflections and stress results of layered and functionally graded composite beams under static load. In the comparison study, the results obtained for a cantilever beam under point load. The Timoshenko beam and the Euler-Bernoulli beam theories are used in the beam model. The energy based Ritz method is used for the solution of the problem and alge...
متن کاملProcessing techniques for functionally graded materials
An overview of the achievements of the German priority program “Functionally Graded Materials (FGM)” in the field of processing techniques is given. Established powder processes and techniques involving metal melts are described, and recent developments in the field of graded polymer processing are considered. The importance of modeling of gradient formation, sintering and drying for the produc...
متن کاملFracture Behavior and Properties of Functionally Graded Fiber-Reinforced Concrete
In concrete pavements, a single concrete mixture design is selected to resist mechanical loading without attempting to adversely affect the concrete pavement shrinkage, ride quality, or noise attenuation. An alternative approach is to design distinct layers within the concrete pavement surface which have specific functions thus achieving higher performance at a lower cost. The objective of this...
