Algorithms for Design and Interrogation of Functionally Gradient Material Objects
Solid Freeform Fabrication (SFF) processes have demonstrated the ability to produce parts with locally controlled composition. In the limit, processes such as Three-Dimensional Printing(3DP) can create parts with composition to the length scale of 100 μm. To exploit this potential, new methods for automatic design of Functionally Gradient Material (FGM) parts need to be developed. This paper pr...

متن کاملTopology Optimisation of Thermomechanical Functionally Graded Materials and Material Interfaces
The work applies topology optimisation to the design of functionally graded materials (FGMs) and materialinterfaces for thermomechanical problems. It is well known, that the mismatch in stiffness and thermal expansioncoefficient of two materials give rise to high stresses at the interface. One way to alleviate this is to use the conceptof FGMs [1]. The FGMs are here designed using t...
متن کاملStress Intensity Factor Determination in Functionally Graded Materials, Considering Continuously Varying of Material Properties
In this paper, the plates made of functionally graded material (FGM) with and without a crack are numerically simulated, employing the finite element method (FEM). The material property variations are defined to be fully continuous; therefore, the elements can be as small as required. For this purpose, variations of the material properties are applied in both the integration points and in the n...
متن کاملGradient Elasticity Theory for Mode III Fracture in Functionally Graded Materials – Part II: Crack Parallel to the Material Gradation
A mode III crack problem in a functionally graded material (FGM) modeled by anisotropic strain gradient elasticity theory is solved by the integral equation method. The gradient elasticity theory has two material characteristic lengths ` and `′, which are responsible for volumetric and surface strain-gradient terms, respectively. The governing differential equation of the problem is derived ass...
