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...

This study provides an insight in the analytical estimation of electric field along surface a stress grading system (SGS) end-winding region electrical machine. An approach is derived for materials (FGMs) having power-law electric-field-dependent conductivity. Despite some limitations, introduced model can be used preliminary analysis SGS with specific geometric and dielectric parameters, both ...

In this paper, the steady-state and transient heat transfer processes of functionally graded materials (FGMs) are analyzed using a coupled thermo-mechanical model in GPU parallel multiphysics finite–discrete element software, namely MultiFracS. First, to handle problem heterogeneous is verified. Then, advantages disadvantages FGMs composite response thermal shock loads compared results indicate...

In the present article, the thermal analysis of the cylinder and the piston in four-cylinder engines, made of functionally graded materials (FGMs), has been performed by using the super element method. The objective of using FGMs in the cylinder and the piston is to increase their performance. FGMs include a combination of ceramics and metals. Inside the cylinder, the ceramic is considered and ...

Functionally graded materials (FGMs) are a good response to those advanced applications that service requirements diverse and require high performance. Additive manufacturing (AM) technology, with its many advantages, including flexibility for complex geometries near-net-shape integration, has attracted special attention in the development of FGMs. In this research, solidification behavior micr...

This study aimed to develop a functionally graded membrane (FGM) to prevent infection and promote tissue regeneration. Poly(l-lactide-co-d,l-lactide) encapsulating platelet-derived growth factor (PDLLA-PDGF) or metronidazole (PDLLA-MTZ) was electrospun to form a nanofibrous layer on the inner or outer surface of a clinically available collagen membrane, respectively. The membrane was characteri...

In this article, the transient dynamic analysis of two dimensional coupled non-Fick diffusionelasticity is carried out in functionally graded materials (FGMs) under shock loading using meshless local Petrov–Galerkin (MLPG) method. By using a unit step function as the test functions on small subdomains of circular shape in the local weak-form, the local integral equations (LIEs) are obtained for...
