Article
Full-text available
Ruled surfaces have been used to create kinetic designs capable of reconfiguring their shapes to adapt to the environment and enhance aesthetic qualities. However, many existing designs require complex mechanical systems and heavy construction. Simplifying the design and construction process using an elastic-kinetic approach is promising but remain...
Article
Full-text available
Topology optimization techniques are typically performed on a design domain discretized with finite element meshes to generate efficient and innovative structural designs. The optimized structural topologies usually exhibit zig-zag boundaries formed from straight element edges. Existing techniques to obtain smooth structural topologies are limited....
Article
Full-text available
Liu et al. (Science, 26 August 2022, p. 975) claim that an advantage of irregular architectured materials is that they are insensitive to damage. We contend that this conclusion is flawed. We further argue that regular architectured materials typically are far superior to irregular ones, before and after damage, in terms of the maximum stress and t...
Article
Full-text available
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...

Kirigami techniques use prescribed arrangements of cuts and fold lines to transform 2D sheet materials into complex 3D forms. These sheet transformations occur via elastic deformations, rigid folding motions, and/or pop-up mechanisms; design techniques for kirigami patterns are correspondingly based on mechanics, kinematics, and physical prototypin...

Most structures around us carry loads. The performance of a structure usually depends on its geometry, material properties, support conditions, and load conditions. In the past decades, various optimization techniques have been developed to modify these ingredients to improve structural performance. However, existing optimization techniques are typ...

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...
Article
Full-text available
Dividing a 2-dimensional sphere uniformly into a large number of spherical polygons is a challenging mathematical problem, which has been studied across many disciplines due to its important practical applications. Most sphere subdivisions are achieved using spherical triangles, quadrangles, or a combination of hexagons and pentagons. However, sphe...

Topology optimization techniques are typically performed on a design domain with predetermined support conditions to generate efficient structures. Allowing the optimizer to simultaneously design supports and to-pology offers new design possibilities to achieve improved structural performance and reduce the cost of supports. However, existing simul...
Article
Full-text available
Ruled surfaces are widely used for architectural forms, as diverse 3D shapes can be conveniently generated by the movement of a straight ruling. There is vast potential to create a rich variety of new architectural forms by introducing curved rulings into ruled surfaces. This paper presents a new method to generate ruled surface variants by making...
Conference Paper
Full-text available
Support locations of a structure in traditional structural design procedures are typically prescribed. A structure with improved structural performance may be obtained by manually adjusting its support locations through a trial-and-error process. However, such an approach is tedious and time-consuming, and the results can be far from the optimal so...
Conference Paper
Full-text available
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...
Article
Origami-inspired metamaterials utilise geometric sheet transformations to generate and control novel material mechanical properties. The majority of research effort has been devoted to straight-crease origami-inspired metamaterials, however curved-crease origami, which allows compliant folding and bending behaviours, has significant potential for a...
Article
Full-text available
The roof–column structural system is utilized for many engineering and architectural applications due to its structural efficiency. However, it typically requires column locations to be predetermined, and involves a tedious trial-and-error adjusting process to fulfil both engineering and architectural requirements. Finding efficient column distribu...

The COVID-19 pandemic has created enormous global demand for personal protective equipment (PPE). Face shields are an important component of PPE for front-line workers in the context of the COVID-19 pandemic, providing protection of the face from splashes and sprays of virus-containing fluids. Existing face shield designs and manufacturing procedur...

This thesis systematically explored the design and utilisation of elastically-bent curved-crease origami. This was achieved by developing a set of curved-crease patterns with consideration of the interaction between material elastic bending energy behaviours and origami developability constraints. The thesis makes the following contributions. Firs...
Conference Paper
Full-text available
Pop-up mechanisms are able to generate complex forms from flexible planar materials. They have successfully been used for 3D micro scale engineering applications, but are not yet utilized for building-scale elements due to the difficulty of scaling planar actuation mechanisms. Separately, building elements formed with large, elastic bending deflect...

Multistate origami can achieve multiple design objectives within a single sheet. Separately, curved-crease origami imparts non-zero principal curvature in the sheet during folding, an attribute which designers have utilized for range of applications. This study investigates the intersection of these two pattern families to create multistate curved-...
Conference Paper
Full-text available
Curved-crease origami is a subset of origami patterns which induce a curvature into a sheet during folding. This property has led to a number of interesting applications in civil engineering and architecture, however concise geometric parametrisation and precise folded fabrication of such components remains an ongoing challenge. In this paper, the...

Accordion patterns are widely used for deployable shelters, due to their simple construction, elegant deployment mechanism, and folded plate form with an inherent structural efficiency. This paper proposes two new accordion-type shelters that use modified geometries to improve on the structural stability and stiffness of the typical accordion form....
