Porous structures such as trabecular bone are widely seen in nature. These lightweight and exhibit strong mechanical properties. In this paper, we present a method to generate bone-like porous infill for additive manufacturing. Our builds upon extends voxel-wise topology optimization. particular, the purpose of generating sparse yet stable distributed interior given shape, propose upper bounds on localized material volume proximity each voxel design domain. We then aggregate local per-voxel...
Inspired by natural cellular materials such as trabecular bone, lattice structures have been developed a new type of lightweight material. In this paper we present novel method to design that conform with both the principal stress directions and boundary optimized shape. Our consists two major steps: first optimizes concurrently shape (including its topology) distribution orthotropic inside maximize stiffness under application-specific external loads; second takes configuration (i.e.,...
A key requirement in 3D fabrication is to generate objects with individual exterior shapes and their interior being optimized application-specific force constraints low material consumption. Accomplishing this task challenging on desktop computers, due the extreme model resolutions that are required accurately predict physical shape properties, requiring memory computational capacities going beyond what currently available. Moreover, fabrication-specific need be considered enable...
Abstract The design of optimal structures and the planning (additive manufacturing) fabrication sequences have been considered typically as two separate tasks that are performed consecutively. In light recent advances in robot-assisted (wire-arc) additive manufacturing which enable addition material along curved surfaces, we present a novel topology optimization formulation concurrently optimizes structure sequence. For this, sets variables, i.e., density field for defining structural...
Liquid crystal elastomers (LCEs), as an intriguing class of soft active materials, exhibit excellent actuation performances and biocompatible properties, well a high degree design flexibility, which have been increasing interest in many disciplines. This review summarizes recent developments this inspiring area, providing overview fabrication methods, schemes, mechanisms, diverse applications LCEs. Firstly, two-stage one-pot synthesis emerging techniques (e.g., 3D/4D printing top-down...
In additive manufacturing, the fabrication sequence has a large influence on quality of manufactured components. While planning is typically performed after component been designed, recent developments have demonstrated possibility and benefits simultaneous optimization both structural layout corresponding sequence. This particularly relevant in multi-axis where rotational motion offers enhanced flexibility compared to planar fabrication. The approach, called space–time topology...
Slender long-span bridges exhibit unique features which are not present in short and medium-span such as higher traffic volume, simultaneous presence of multiple vehicles, sensitivity to wind load. For typical buffeting studies under turbulence, no load was typically considered simultaneously with wind. Recent bridge/vehicle/wind interaction highlighted the importance predicting bridge dynamic behavior by considering bridge, actual load, a whole coupled system. Existent analysis, however,...
Overloaded trucks, including some extra heavy often cause serious threats to bridges, such as deterioration, fatigue damage, or even collapse. Compared with the standard traffic design loads in specifications, actual characteristics of overloaded truck weight and types, are very difficult predict define. These not specific only location. Rather, they depend on economy, regulations, law enforcement, also vary over time a result uncertainties at given In current study, long-term monitoring...
Abstract Virtual cutting of deformable bodies has been an important and active research topic in physically based modelling simulation for more than a decade. A particular challenge virtual is the robust efficient incorporation cuts into accurate computational model that used body. This report presents coherent summary state art bodies, focusing on distinct geometrical topological representations body, as well specific numerical discretizations governing equations motion. In particular, we...
White etching layer (WEL) is a frequently observed microstructural phenomenon in rail surface, formed during dynamic wheel/rail contact. It considered as one of the main initiators for rolling contact fatigue cracks. There are several hypotheses formation mechanism WEL. However, due to complicated conditions, none directly proven. Currently, most popular refer either martensitic WEL by phase transformations or nanocrystalline ferritic severe plastic deformation. In this work, transformation...
Real-time proprioception is a challenging problem for soft robots, which have virtually infinite degrees of freedom in body deformation. When multiple actuators are used, it becomes more difficult as deformation can also occur on caused by interaction between each other. To tackle this problem, we present method article to sense and reconstruct 3-D pneumatic robots first integrating low-cost sensors inside the chambers then using machine learning convert captured signals into shape...
Recent advances in 3D printable micro-architected materials offer unprecedented possibilities for the development of highly tailored orthopaedic implants. These devices, which are typically made from fully solid materials, significantly alter load transmission to surrounding bone tissue, potentially leading interface instability and resorption. In this work, we present computational methods synthesize three dimensional (3D), patient-specific, implants with heterogeneous micro-architecture....
Abstract As key interfaces for the disabled, optimal prosthetics should elicit natural sensations of skin touch or proprioception, by unambiguously delivering multimodal signals acquired to nervous system, which still remains challenging. Here, a bioinspired temperature‐pressure electronic with decoupling capability (TPD e‐skin), inspired high‐low modulus hierarchical structure human skin, is developed restore such functionality. Due bionic dual‐state amplifying microstructure and contact...

Several techniques exist to automatically synthesize a 2D image resembling an input exemplar texture. Most of the approaches optimize new so that color neighborhoods in output closely match those input, across all scales. In this paper we revisit by-example texture synthesis context additive manufacturing. Our goal is generate not only colors, but also structure along surfaces: given indicating 'solid' and 'empty' pixels, similar pattern surface. The core challenge guarantee fully connected,...
Offsetting-based hollowing is a solid modeling operation widely used in 3D printing, which can change the model's physical properties and reduce weight by generating voids inside model. However, lead to additional supporting structures for fabrication interior voids, cannot be removed. As consequence, result of affected these when applying optimize different models. This paper proposes support-free framework overcome difficulty fabricating solid. The challenge computing decomposed into...
