Hybrid function representation for heterogeneous objects

Constructive Representation of Heterogeneous Objects

This paper proposes a constructive representation scheme for heterogeneous objects (or FGMs). In particular, this scheme focuses on the construction of complicated heterogeneous objects, guaranteeing desired material continuities at all the interfaces. In order to create various types of heterogeneous primitives, we first describe methods for specifying material composition functions such as ge...

Representation and CAD Modeling of Heterogeneous Objects

This paper presents a modeling scheme for objects containing multiple materials or functionally graded materials (FGM), i.e. heterogeneous objects. The material composition variations under this modeling scheme are controlled by some reference features termed as “grading sources”. The “grading source” gathers the type of grading, position of grading and a material grading function for controlli...

Representation and Processing of Heterogeneous Objects for Solid Freeform Fabrication

Solid Freeform Fabrication (SFF), also referred to as Layered manufacturing (LM), is a new method of fabrication. Unlike conventional manufacturing (e.g., CNC machining), where a part is fabricated by selectively removing material from a workpiece, in SFF, a part is built by depositing material, layer-by-layer, under computer control. Solid Freeform Fabrication is in principle a 2.5D process st...
