Abstract

In this paper, a new feature-based material blending method is proposed to represent and design heterogeneous objects. Geometric features dictating the material variation are defined as material governing features to control material composition inside the objects. Interrelations between the material governing features and material attributes are established by constraining the geometric and material features and retained in the object model. Using these relationships, variant heterogeneous objects are developed easily by changing the geometric and material features of the heterogeneous object. Geometric methods are developed to blend not only the geometric features but also the property requirements at each of the feature. To obtain the best material variation inside the object, an optimization-based solution method based on the object's functional requirements are developed. Implementation and illustrative examples are also presented in this paper.
