In the paper, a novel magneto-electro-elastic model of bi-directional (2D) functionally graded materials (FGMs) beams is developed for investigating nonlinear dynamics. It shown that asymmetric modes induced by 2D FGMs may significantly affect dynamic responses, which tremendously different from previous studies. Taking into account geometric nonlinearity, equation motion and associated boundar...

Functionally graded materials (FGMs) are composed of metals and ceramics in which the distribution material components varies according to a particular volumetric function. FGMs often used high-temperature applications. In our study, models were created Artificial Neural Network depending on equivalent stress levels compositional gradient exponent, is most important parameter determining thermo...

Fecal glucocorticoid metabolite (FGM) assays are a popular means of monitoring adrenocortical activity (i.e., physiological stress response) in wildlife. Species-specific differences in glucocorticoid metabolism and excretion require assay validation, including both laboratory and biological components, before assay use in new species. We validated a commercially available radioimmunoassay (MP ...

This paper presents an overview on applications of hybrid finite element method to thermal analysis of heterogeneous materials. Recent developments on the hybrid fundamental solution based finite element model (FEM) of heat transfer in nonlinear functionally graded materials (FGMs) and composite materials are described. Formulations for all cases are derived by means of modified variational fun...

Dynamic crack propagation assessment in functionally graded materials (FGMs) with micro-cracks is accomplished using bond-based Peridynamics (PD). The dynamic fracture behaviour of various FGMs’ material models studied Kalthoff–Winkler experiment. growth predictions and associated damage the specimen under loading conditions are considered. effect near macro-crack tips on toughening mechanism e...

Abstract We present a physics-informed deep learning model for the transient heat transfer analysis of three-dimensional functionally graded materials (FGMs) employing Runge–Kutta discrete time scheme. Firstly, governing equation, associated boundary conditions and initial condition FGMs with exponential material variations are presented. Then, collocation method integration scheme is introduce...

Functionally gradient materials (FGMs) with gradual and continuous changes of their properties in one or more dimensions are useful in a wide range of applications. However, obtaining such materials with accurate control of the gradient, especially when the gradient is nonlinear, is not easy. In this work, frontal polymerization (FP) was exploited to synthesize polymeric FGMs. We demonstrated t...

In functionally graded materials (FGMs) fabricated using directed energy deposition (DED) additive manufacturing (AM), cracks may form due to interdendritic stress during solidification, the formation of deleterious phases, or buildup residual stresses. This study builds on our previously proposed concept three-alloy FGM system feasibility diagrams for identification gradient pathways that avoi...
