Multi-material products are getting increasingly popular in recent years. Yet no systems have been developed to support the design of such products. In this article, a haptic-based method for designing multi-material products is proposed. The proposed method consists of three main parts: haptic painting/marking, boundary smoothing/fitting, and volume decomposition. A prototype system based on the three parts has been implemented using a haptic input device. The haptic device provides an intuitive user interface for quick volume mark-up in a multi-material product by direct mesh painting. Each painted region represents a material volume whose boundary can be automatically traced. The boundary points are then used as control points for Catmull-Rom spline fitting. To constrain a spline to the original mesh surface, the spline is projected onto the mesh. Now, using the boundary splines, volume decomposition can be done automatically when needed. Each decomposed volume can be assigned a different material or colour. The numerous iterations of volume mark-up and decomposition in the early stage of multimaterial product design can now be made easy and effective using the proposed method.

“…[1][2][3][4] To summarize, these include: (i) the initial (high) quality of the stiff ceramic particles used, which must be free of stress concentration sites and internal defects, (ii) the presence of a ductile matrix free of brittle second phases, (iii) a capacity for composite bulk plastic deformation, made possible in spite of the high ceramic loadings by the fact that only the metal is continuous in their microstructure. These characteristics combined produce, in the composite, a…”

Multi‐Criteria Material Selection of Monolithic and Multi‐Materials in Engineering Design

The benefits of combining different homogeneous materials to give heterogeneous materials have been recognized since our early history; straw-reinforced brick and goat hairreinforced pottery are examples. [1] Such combinations are known as multi-materials [2] or hybrid materials. [3] A useful working definition [4] is "a combination of two or more materials in a pre-determined configuration and scale, optimally serving a specific engineering purpose". Established examples are particular and fiber-reinforced composites, [1,5] like CFRP and GFRP, and sandwich structures. Barbero classifies multi-materials -composites as he terms them -into three classes: reinforced composites, laminated composites and hybrid composites. [6] Ashby includes lattice materials and segment materials in addition to reinforced composites and sandwich structures. [7] Four classes of multi-materials, following Ashby, [7] are presented in Figure 1. This article describes a tool to support designers in comparing the performances of multi-materials with those of other materials and to guide their selection for a given application. One particular type, sandwich panels, is chosen as a focus to implement and illustrate the methodology.Approaches to multi-material selection: Designers should ideally explore the widest possible range of conceptual solutions before selecting one. Thus, the material search space should be as broad as possible at the conceptual design stage, as shown in Figure 2. As the design proceeds this space is narrowed, culminating in a single choice.Multi-material selection is more complicated than that of monolithic materials for two reasons: first, because the configuration in which the constituents are to be combined must be chosen, and, second, because, in optimizing the combination, the number of free variables is greater -it now includes the relative volumes of the two constituents, their configuration and their scale. What is needed is a way of exploring and optimizing these. Designers can then bring multi-materials into consideration in either of two broad approaches, as mentioned by Phillips [8] and Quinn. [9] Catalogue approach: Particulate and fibrous compositesthe best known hybrids -can be included in a materials database in the same way as monolithic materials, allowing direct comparison and selection by established material-selection methodologies. [7] An example is the Cambridge Engineering Selector (CES) database, [10] which includes some 200 composites and foams. Work on developing a knowledge-based system to assist composites selection has also been undertaken. [11] This allows selection from among existing, commercially available composites, but it does not allow for optimization; to do that requires ways of exploring all feasible combinations of material, configuration, and, where relevant, scale.The proposed approach: The alternative is to think of multimaterials as the combination of several constituents. This approach might well lead to a better solution since the multimaterials can be tailored to meet t...
