Functionally graded graphene reinforced composite structures: A review

Engineering Structures, 2020
Owing to their superior mechanical properties, e.g. exceptionally high Young's modulus, high strength, large specific surface area, and good thermal conductivity, graphene and its derivatives such as graphene platelets (GPLs) are excellent reinforcing nanofillers for composite materials.

Functionally Graded Structures

2020
In the present chapter functionally graded materials (FGMs) and structures are presented. In particular, the static and free vibration problems of Timoshenko beams and Mindlin plates are studied. The buckling problem for both structures can be developed following analogous problems presented in Chap. 10 for Timoshenko beams and in Chap.

Mechanical properties of functionally graded hierarchical bamboo structures

Acta Biomaterialia, 2011
This paper presents the results of a series of multi-scale experiments and numerical models concerning the mechanical properties of moso culm functionally graded bamboo structures. On the nano- and microscales, nanoindentation techniques are used to study the local variations in the Young's moduli of moso culm bamboo cross-sections.

Kriging-based optimization of functionally graded structures

Structural and Multidisciplinary Optimization, 2021
This work presents an efficient methodology for the optimum design of functionally graded structures using a Kriging-based approach. The method combines an adaptive Kriging framework with a hybrid particle swarm optimization (PSO) algorithm to improve the computational efficiency of the optimization process.

Sample-Based Synthesis of Functionally Graded Material Structures

Journal of Computing and Information Science in Engineering, 2017
Spatial variation of material structures is a principal mechanism for creating and controlling spatially varying material properties in nature and engineering. While the spatially varying homogenized properties can be represented by scalar and vector fields on the macroscopic scale, explicit microscopic structures of constituent phases are required to ...

Porous Thermoelectric Materials with Functionally Graded Structures

Materials Science Forum, 1999
Porous thermoelectric devices utilizing heat convection by gas flow through the porous device has been proposed. Functionally gradation of thermoelectric and porous properties can satisfy with the requirment for the porous device. However, because many thermoclectric materials such as FeSi 2 , (Bi,Sb) 2 Te 3 and PbTe are generally brittle, development
