Many materials require functionally graded cellular microstructures whose porosity is engineered to meet specific requirements of diverse applications (e.g. polymers and/or ceramics that mimic biological material such as soft tissue and bone). It has been shown in previous work that the bubble growth rate of a polymeric foam can be influenced by the surrounding acoustic environment and, once so...
Abstract In this article, the nonlinear dynamic responses of sandwich functionally graded (FG) porous cylindrical shell embedded in elastic media are investigated. The studied here consists three layers, which outer and inner skins made solid metal, while core is FG metal foam. Partial differential equations derived by utilizing improved Donnell’s theory Hamilton’s principle. Afterwards, Galerk...
In this paper, we examine prospects for the manufacture of patient-specific biomedical implants replacing hard tissues (bone), particularly knee and hip stems and large bone (femoral) intramedullary rods, using additive manufacturing (AM) by electron beam melting (EBM). Of particular interest is the fabrication of complex functional (biocompatible) mesh arrays. Mesh elements or unit cells can b...
Graded material design strategy has been exploited to achieve enhanced mechanical performance compared their uniform counterpart. Using a combined numerical and experimental approach, we investigated the effects of three graded designs on compressive 3D printed architected polymer foams. The foam is composed beam binders spherical shells, which have pronounced under large deformations. It was f...
