Metamaterials are artificial materials designed to exhibit effective material parameters that
go beyond those found in nature. Composed of unit cells with rich designability that are …

Manufacturing-oriented topology optimization has been extensively studied the past two
decades, in particular for the conventional manufacturing methods, for example, machining …

The rise of machine learning has fueled the discovery of new materials and, especially,
metamaterials—truss lattices being their most prominent class. While their tailorable …

Inspired by crystallography, the periodic assembly of trusses into architected materials has
enjoyed popularity for more than a decade and produced countless cellular structures with …

Biomaterials display microstructures that are geometrically irregular and functionally
efficient. Understanding the role of irregularity in determining material properties offers a …

Metamaterials are emerging as a new paradigmatic material system to render
unprecedented and tailorable properties for a wide variety of engineering applications …

Material properties can be tailored through modification of their geometry or architecture.
With this concept, a lot of smart materials, metamaterials, and smart structures have been …

Porous structures such as trabecular bone are widely seen in nature. These structures are
lightweight and exhibit strong mechanical properties. In this paper, we present a method to …

Abstract Three-dimensional printing (3DP) technology has gained an increased popularity in
making prototypes in all types of manufacturing industries including automotive, healthcare …

We present a two-scale topology optimization framework for the design of macroscopic
bodies with an optimized elastic response, which is achieved by means of a spatially-variant …
