Injection molded components with functionally graded foam structures – Procedure and essential results

Production and Analysis of Injection Molded Micro-Optic Components

Injection molding is a manufacturing technique that, through filling of a mold cavity (typically made from steel or aluminum alloys) with molten polymer, produces plastic parts. The geometry of the mold cavity is identical to the desired part shape, after taking into account thermal shrinkage. This manufacturing process is an economical and reliable way to mass-produce a variety of parts. Tradi...

Topology Optimization Design of Functionally Graded Structures

1. Abstract Functionally Graded Materials (FGMs) possess continuously graded material properties and are characterized by spatially varying microstructures. Such materials are studied in conjunction with the concept of topology optimization design which determines holes and connectivities of the structure by adding and removing material in the extended fixed design domain. The objective is to d...

Modeling and Analysis of Functionally Graded Materials and Structures

This paper presents a review of the principal developments in functionally graded materials (FGMs) with an emphasis on the recent work published since 2000. Diverse areas relevant to various aspects of theory and applications of FGM are reflected in this paper. They include homogenization of particulate FGM, heat transfer issues, stress, stability and dynamic analyses, testing, manufacturing an...

Optimal sintering procedure to fabrication of functionally graded Hydroxyapatite-

Functionally graded metal-ceramic composite was fabricated by pressure-less sintering. The pure metallic component (Ti) and the pure ceramic component (HA) were located at the ends of a cylindrical specimen. Titanium and-Hydroxyapatite were utilized as a metallic and ceramic layer. The target sample thickness was 6 mm with radius cylindrical 20 mm. The sample was made from the cylindrical type ...
