Mixed-Mode Crack Propagation in Functionally Graded Materials
… parameters describing the crack tip fields in functionally graded materials (FGMs) include stress intensity factors (SIFs) and T-stress (non-singular stress). These two fracture parameters are important for determining the behavior of a crack under mixed-mode loading conditions in brittle FGMs …

Design and development of a powder mixing device used in the deposition of high velocity oxy-fuel (HVOF) thermal spray functionally graded coatings; Kabir Al Mamun
The application of Functionally Graded Materials (FGMs) is quite difficult, but thermal spray processes like Plasma spray have demonstrated their unique potential in producing graded deposits, where researchers have used twin powder feed systems to mix different proportions of powders. However the …

Design of functionally graded compliant mechanisms using topology optimization
… applies topology optimization to create feasible functionally graded complaint mechanism designs with the aim of improving structural performance compared to traditional homogeneous compliant mechanism designs. Structural performance is assessed with respect to mechanical/geometric advantage and …

Free Vibration of Bi-directional Functionally Graded Material Circular Beams using Shear Deformation Theory employing Logarithmic Function of Radius
… without sacrificing strength is to make them of Functionally Graded Materials (FGMs) that are composites with continuously varying material properties in one or more directions. In this thesis, we study free vibrations of FGM circular beams by using a logarithmic shear deformation theory that …

Structural and Vibration Analysis of Polymeric Functionally Graded Plates
Functionally graded materials (FGMs) are advanced engineered materials whereby material composition and properties vary spatially in the macroscopic length scale. Accurate analytical and numerical models for prediction of mechanical behaviour and damage of the FG plate are required as their …

Fatigue crack propagation in functionally graded materials
Propagation of cracks in functionally graded materials (FGMs) under cyclic loading was investigated via experiments and finite element (FE) analysis. Alumina-epoxy composites with an interpenetrating-network structure and tailored spatial variation in composition were produced via a multi-step …

From Functionally Graded to Grain-Boundary-Decorated Nanograined Alloys: a New Approach to Bulk Lightweight Alloy Design via Friction Stir Processing
Lightweight structural materials offer an alternative strategy to combat global climate change. However, lightweighting often compromises material strength. This limitation can be mitigated by refining grains to ultrafine or nanocrystalline scales (<100 nm). Despite their advantages, the widespread …
