Despite the increasing interest in topological interlocking structures made of identical elements, only one type of interlocking brick has been extensively studied so far, with very limited focus on their dynamic behaviour. In this paper, a new design of interlocking brick was proposed, which had a symmetrical geometry with four curved side surface...

In this paper we propose a general method for creating a new type of hierarchical structures at any level in both 2D and 3D. A simple rule based on a rotate-and-mirror procedure is introduced to achieve multilevel hierarchies. These new hierarchical structures have remarkably few degrees of freedom compared to existing designs by other methods. Mor...

In this paper we study a new type of interlocking brick recently proposed by the authors. The brick has a symmetrical geometry with four concavo-convex side surfaces for the interlocking purpose. Drop weight tests have been conducted to investigate the mechanical response of interlocking assembly plates by applying different levels of impact force...

This paper presents an extensive numerical study on the impact behaviour of plate-like assemblies made of interlocking concrete bricks. In the proposed 3D finite element model, a damage based concrete model is employed with considerations of strain rate effect and concrete failure criteria. Boundary conditions are appropriately defined to simulate...

In this study, the mechanical responses of an assembly plate made of topologically interlocking concrete bricks with rubber as soft interfaces are investigated. The principle of topological interlocking is combined with the concept of hybrid material design. A series of quasi-static tests are conducted to compare the mechanical behaviour of the hyb...

A Goldberg polyhedron is a convex polyhedron made of hexagons and pentagons that have icosahedral rotational symmetry. Goldberg polyhedra have appeared frequently in art, architecture, and engineering. Some carbon fullerenes, inorganic cages, viruses, and proteins in nature exhibit the fundamental shapes of Goldberg polyhedra. According to Euler's...

Ribbed floor systems, which include ribbed slabs and columns, are used extensively to enhance thestructural performance of buildings. With the emerging topology optimization and advancedmanufacturing techniques, the material usage and construction process of the ribbed floor systems canbe improved significantly to achieve higher efficiency and sust...

Goldberg polyhedra have been widely studied across multiple fields, as their distinctive pattern can lead to many useful applications. Their topology can be determined using Goldberg’s method through generating topologically equivalent structures, named cages. However, the geometry of Goldberg polyhedra remains underexplored. This study extends Gol...

Dividing a sphere uniformly into equal-area or equilateral spherical polygons is useful for a wide variety of practical applications. However, achieving such a uniform subdivision of a sphere is a challenging task. This study investigates two classes of sphere subdivisions through numerical approximation: (i) dividing a sphere into spherical polygo...

Tessellations have been utilised for many novel architectural applications, as they can create striking surfaces by repeating a small number of different elements. However, most tessellations are limited to periodic arrangements and planar configurations. This study systematically addresses these two limitations by developing a new type of nonperio...

The design and manufacture of structural nodes for gridshell structures are complicated due to complex geometries and loading conditions. The validation of the design concepts of these nodes is even more challenging, because complex design loads are difficult to be applied in a laboratory test. In this paper, a testing rig is proposed and manufactu...

In this paper, two new design approaches are proposed to design structural nodes of complex shapes for gridshell structures, seeking improved structural performance and design efficiency by using the transitional section method and the bi-directional evolutionary structural optimization (BESO) method, respectively. Detailed design methodologies are...
