Functionally graded scaffold (FGS) can flexibly regulate the mechanical properties of bone and holds great promise for offering multifunctional responses orthopaedic implants. Heterogeneous FGSs constructed by skeletal sheet triply periodic minimal surfaces (TPMSs) have been proposed in this study. The diversified deformation mechanisms TPMS-FGSs showed superior stability, energy absorption eff...

Functionally Graded Scaffolds (FGSs) are porous biomaterials where porosity changes in space with a specific gradient. In spite of their wide use in bone tissue engineering, possible models that relate the scaffold gradient to the mechanical and biological requirements for the regeneration of the bony tissue are currently missing. In this study we attempt to bridge the gap by developing a mecha...

Recently, Functionally Graded Scaffolds (FGSs) have attracted a lot of attention as bone replacements due to their gradient porosities as well as a bone structure. In present study titanium functionally graded scaffolds (FGSs) were fabricated by powder metallurgy route using Mg and carbamide as space holders. The arranged layers with 20, 40 and 60 Vol.% porosities were compacted in steel die us...

An accurate solution procedure based on the three-dimensional elasticity theory for the free vibration analysis of Functionally Graded Sandwich (FGS) plates is presented. Since no assumptions on stresses and displacements have been employed, it can be applied to the free vibration analysis of plates with arbitrary thickness. The two-constituent FGS plate consists of ceramic and metal graded thr...

in this paper, the influence of the constituent volume fractions by changing the values of the power-law exponent with uniform pressure on the vibration frequencies of reinforced functionally graded cylindrical shells is studied. the fgm shell with ring is developed in accordance to the volume fraction law from two constituents namely stainless steel and nickel. these constituents are graded th...

OBJECTIVES/HYPOTHESIS The severity of Bell's facial palsy is monitored through physician-graded instruments, like the House-Brackmann or Sunnybrook Facial Grading System (FGS). These instruments primarily measure the degree of facial muscle impairment and its resulting asymmetry, but neglect the other functional aspects of facial disability. The aim of this study is therefore to compare the FGS...

Semisolid powder processing (SPP) is a promising approach for near net-shape forming of features in micro/meso-scale. By combining the concept of forming in the semisolid state and conventional powder metallurgy, SPP provides a novel solution to various processing and materials engineering challenges faced in micromanufacturing. Replacing bulk materials with powdered materials adds a new dimens...

this paper deals with the determination of displacement function and thermal stresses of a finite length isotropic functionally graded hollow cylinder subjected to uniform temperature field. the solution of the governing thermoelastic equation is obtained, as suggested by spencer et al. for anisotropic laminates.  numerical calculations are also carried out for fgm (functionally graded material...

this paper deals with local buckling analysis of rectangular functionally graded material plates using finite strip method and based on classical plate theory. the modulus of elasticity of the plate is assumed to vary according to a power-law distribution in terms of the volume fractions of the constituents. the principle of minimum total potential energy is employed to obtain stiffness and sta...
