Heterogeneous objects are composed of different constituent materials. In these objects,
material properties from different constituent materials are synthesized into one part …

The task of modeling material heterogeneity (composition variation) is a critical issue in the
design and fabrication of heterogeneous objects. Existing methods cannot efficiently model …

Heterogeneous objects, composed of different materials, are increasingly being used in
engineering applications. Also, a new fabrication method called Layered Manufacturing …

Advances in materials and rapid prototyping technology, makes developing rapid-prototype
heterogeneous parts possible. This paper proposes a finite element-based approach for …

We propose a universal approach to the problem of computer modeling of shapes with
continuously varying material properties satisfying prescribed material conditions on a finite …

Heterogeneous object design is an active research area in recent years. The conventional
CAD modeling approaches only provide geometry and topology of the object, but do not …

The possibility to attain diverse applications from heterogeneous objects calls for a generic
and systematic modeling approach for design, analysis and rapid manufacturing of …

Heterogeneous object design is an active research area in recent years. This research
