“…It also allows to tailor material properties to a specific application, for optimal design. In this approach the word "material" is used as an umbrella term for both its original meaning and more broadly, like for example galvanized steel-indivisible material from which a given object is manufactured or a representative of a given microstructure with specific set of properties (Kromm et al 2002;Ashby and Bréchet 2003). In scope of this paper the term "material" is used in its conventional meaning in regard to bulk material and additionally as phases with specific sets of material properties obtained via multiscale modeling of specific periodic microstructures.…”

Hybrid multiphase materials exhibit a wide range of desirable properties, which may be tailored to the needs of their user or application. Modern solutions often use advanced smart materials with specific properties, which in some cases allow the development of devices previously impossible to manufacture due to restrictions of conventional materials. There is ongoing research on multiphase materials composed of phases with differing Poisson’s ratios, which have increased elastic modulus compared to their respective monophase components. Precise analysis of multiphase materials composed of periodic microstructures is possible with the use of multiscale modeling methods and numerical homogenization of individual phases’ geometric structures into homogenous materials retaining the properties of their representative volume elements. Auxetic materials behavior under loading differs from conventional materials. Their Poisson’s ratio value is negative, which means that when they are uniaxially stretched they both elongate and expand laterally, and while uniaxially compressed they both shorten and shrink laterally. While seemingly changing volume, their density remains constant in microscale. Deformation causes the gaps in auxetics patterned structure to change shape and size, but the actual material of the structure remains unchanged. This paper presents the results of development of a multiphase hybrid material with auxetic phase, in two variants. First, with the goal of maximization of the material’s elastic modulus. Second, to obtain a zero-value effective Poisson’s ratio. Different patterns of phases distribution in the material were analyzed. A few different auxetic structures were taken into consideration. Optimization utilized numerical simulation based on finite element method.

“…1 The development of architectured approach of material design has genesis in the design concept of hybrid materials, where two or more materials are assembled in a manner to achieve the properties, which are not achievable by any of the individual constituent. 2 The processing of architectured materials is one of the challenging problems in the material science. There have been several approaches for the development of architectured materials, namely, cocasting of two different alloys, 3 gas carburisation reactions to non-isothermal situations combined with masking technology, 4 surface deformation 5 or geometric induced strain hardening.…”

In the traditional physical metallurgy approach, the microstructure evolves as the product of the interactions between composition and process parameters, controlled by thermodynamic and kinetic conditions. Thus, the approach is more evolutionary than constructive. An architecturally designed microstructure implies planning, design and construction of microstructure considering nature, size, morphology and distribution of the constituent phases on a suitably conceived topological framework. This investigation puts emphasis on performance driven construction of the microstructure with precise calculation of response of microstructural constituents under the given loading conditions. With the aforesaid motivation, the present study elucidates the principle involving microstructural generation by Voronoi tessellation and subsequent elastoplastic finite element simulation. In addition, the present study also explores the correlation between architecturing and initiation of instability in the microstructure through genetic programming.

“…H ybrid materials (Fig. 1) are combinations of two or more materials, or of materials and space, assembled in such a way as to have attributes not offered by any one material alone 1,2 . Particulate and fiber composites are examples of one type of hybrid, but there are many others: sandwich structures, foams, lattice structures, segmented structures, zero‐expansion material, and more.…”

Hybrid Materials to Expand the Boundaries of Material‐Property Space

The materials we use today for mechanical design are the outcome of at least 3000 years of development, much of it empirical but much the outcome of systematic science. Both approaches have been motivated by the desire for stiffer, stronger, more durable, and lighter structures, progressively populating material property “space”. We first examine the extent to which this space is now filled and estimate the ultimate constraints on this filling. Strategies for expanding the filled regions further include hybrid material design—making materials by combining two or more monolithic materials in chosen configurations and connectivity. Here we explore two classes of hybrid—lattice materials and sandwich structures—developing ways of comparing their properties with those of conventional monolithic materials. The comparison reveals the potential of hybrids. This paper builds on ideas that have grown from a long and rewarding collaboration with Tony Evans with whom it has been a privilege to have worked.
