“…Previously, lateral load was found to enhance the bending stiffness and strength of assemblies of cubes or other polyhedra. [17] Numerical simulations of this effect for assemblies of cubes were reported by Schaare [9] and Brugger et al [18] . To exclude this effect, the inner frame was adjusted in such a way as to just touch the outer row of interlocking blocks without exerting a lateral force on the interlocked structure.…”

In the present paper, the force‐fit connection of discrete ceramic components by means of geometrically interlocking surfaces is studied. These surfaces possess a concavo‐convex topology permitting assembly of structures in which each individual element is kinematically locked by its neighbors. Such structures have a tuneable bending stiffness, allow for large deformations and are tolerant to missing or destroyed elements. These properties of topologically interlocked structures make them particularly attractive in construction with brittle materials. The elements used were produced by freeze gelation of ceramic slurries, leading to near net shape with the coefficient of shrinkage below 3%. It is shown that planar assemblies of interlocked ceramic elements can withstand flexural deflections up to a ten‐fold of those a solid plate from the same material can sustain. The response of these structures to concentrated load can be divided into an elastic and a quasi‐plastic, i.e., irreversible, part. After the point of maximum load, the interlocked structures investigated were still able to withstand further deformation, whereas solid plates showed brittle failure.

“…Such systems establish equilibrium through compression forces. TIA is largely researched in single-layer 7 and multi-layer assemblies. 8 Some researchers hypothesize the mechanical responses of TIA are controlled by the geometry of the interlocking elements, their surfaces, and their local surface patterns, 9 while others see it as a method that opens new avenues for large-scale mortar-free construction.…”

Architectured Materials in Nature and Engineering

Architectured materials involve geometrically engineered distributions of microstructural phases at a scale comparable to the scale of the component, thus calling for new models in order to determine the effective properties of materials. The present chapter aims at providing such models, in the case of mechanical properties. As a matter of fact, one engineering challenge is to predict the effective properties of such materials; computational homogenization using finite element analysis is a powerful tool to do so. Homogenized behavior of architectured materials can thus be used in large structural computations, hence enabling the dissemination of architectured materials in the industry. Furthermore, computational homogenization is the basis for computational topology optimization which will give rise to the next generation of architectured materials. This chapter covers the computational homogenization of periodic architectured materials in elasticity and plasticity, as well as the homogenization and representativity of random architectured materials.
