Optimization of material properties needed for material design of components made of multi-heterogeneous materials

Heterogeneous object modeling with material convolution surfaces

“…Most of the researchers had proposed ''add-in'' extensions within commercial CAD systems for modeling heterogeneous objects [3,9,16,12]. This addition admits only minor changes within an existing framework; however, the overall system structures cannot be changed.…”

“…The complex heterogeneous objects can be generally classified into three types: (i) objects with complex geometries and simple 1D material-distributions; (ii) objects with compound (2D or 3D) material-distributions, but simple/regular geometries; and (iii) objects with complex geometries as well as complex and irregular material-distributions. In comparison with other representations [7,13,28,3,12], the proposed approach is capable of modeling complex heterogeneous objects with complex geometry or/and compound and irregular material-distributions. A few examples of modeling complex heterogeneous objects are demonstrated to show the validity of the proposed approach.…”

“…Marsan and Dutta [11] developed tensor product solids through heterogeneous solid modeling. Zhang et al [12] optimized the material properties of components made of different materials. Feng et al [13] developed a computer aided design (CAD) modeling system for the fabrication of functional components with multi-material properties.…”

Characteristics of Oilwell Cement Slurry Using CMC

“…Zhang et al (2004) developed a detailed approach for determining the optimal material properties in a component according to its functional requirements. Therefore, optimization carries common conceptual rules that different research themes may share.…”

Fractal raster tool paths for layered manufacturing of porous objects

“…The accuracy of these models is resolution-and granularity-dependent and the memory use is huge. Voxel-based evaluated models (Chandru et al 1995, Bhashyam et al 2000, Chen and Tucker 2000, Todd 2000, Park et al 2001, Cho and Ha 2002, Zhang 2004) represent heterogeneous objects as a collection of voxels, with each voxel having specific material distribution data. Unevaluated models generally do not involve intensive spatial decompositions/ subdivisions or discretisations and, theoretically, can provide sufficient fidelity in geometries and material distributions (Liu 2000, Huang et al 2002, Siu and Tan 2002, Biswas et al 2004, Cho and Shin 2004, Liu et al 2004, Zhu 2004, Kou and Tan 2005, Samanta and Koc 2005.…”
