Functionally Graded Materials (FGMs) offer discrete or continuously changing properties/compositions over the volume of parts. The widespread application FGMs was not rapid enough in past due to limitations manufacturing methods. Significant developments technologies especially Additive Manufacturing (AM) enable us nowadays manufacture materials with specified changes volume/surface components....

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...

functionally gradedpoisson’s ratio structures have been developed for critical protection. in thispaper, the static bending and buckling of fgpr nanoscale beam are studied basedon the nonlocal timoshenko beam model, in which both young’s modulus andpoisson’s ratio are assumed to vary continuously in the thickness direction. byutilizing total potential energy principle, equilibrium equations are...

this paper investigates the effect of different methods of carbon nanotubes distribution in a thin matrix on static and dynamic behavior of the nanocomposite. five different symmetric patterns of distribution are considered, including four parabolic patterns and a linear one. for each pattern, the effective mechanical properties of the resultant nanocomposite are calculated using the rule of mi...
