Abstract Maintaining the integrity and longevity of structures is essential in many industries, such as aerospace, nuclear, and petroleum. To achieve the cost-effectiveness of large-scale systems in petroleum drilling, a strong emphasis on structural durability and monitoring is required. This study focuses on the mechanical vibrations that occur in rotary drilling systems, which have a substantial impact on the structural integrity of drilling equipment. The study specifically investigates axial, torsional, and lateral vibrations, which might lead to negative consequences such as bit-bounce, chaotic whirling, and high-frequency stick-slip. These events not only hinder the efficiency of drilling… More >

Abstract Laser powder bed fusion (L-PBF) exhibits many technological opportunities for producing high-performance metallic parts with tailored architectures. However, fabrication of suitable composite powders possessing good flowability, controllable particle size and distribution is a currently prerequisite and main challenge. In this work, two novel techniques, namely freeze-dry pulsated orifice ejection method (FD-POEM) [1] and ultrafine bubble (UFB)-assisted heteroagglomeration [2], have been developed to fabricate uniform composite powders. By taking MoSiBTiC alloy powders as an example, the working principle of FD-POEM process was firstly illustrated. The spherical FD-POEM particles were consisted of typical mesh structures induced by… More >

Abstract NiCoCr medium-entropy alloys (MEAs) with controlled interstitial C contents were fabricated by using powder bed fusion-type additive manufacturing (AM) process. And the microstructure, mechanical properties, and high temperature oxidation resistance of in-situ carbide-reinforced NiCoCr Medium alloy were investigated. The initial microstructure shows that both AM-built interstitial C-doped MEAs had a heterogeneous grain structure and epitaxial growth grains along the building direction. The analysis of electron channeling contrast images showed a large amount of nano-sized precipitates (in-situ precipitates) distributed at the sub-structure boundaries formed by a dislocation network, and a large number of stacking faults were simultaneously observed inside the sub-structure.

Abstract Natural nanofibers, e.g., cellulose nanofiber (CNF) of plant, collagen fibril in human body and fibroin fiber in spider silk, show interesting and distinctive atomistic mechanisms in deformation under mechanical loading as well as exhibition of extraordinary strength. These fibers are comprising more larger bulk and wire materials by constructing structural hierarchy. However, the initiation of unique behavior of these materials largely originates from atomic-scale and chemical energetics in loading. Besides, the experimental approach is often difficult and is too limited to reveal the basic mechanism. Therefore, it is crucial to clarify atomic behavior of these… More >

Abstract The emergence of 4D printing introduces stimuli-responsive, shape-changing capabilities through additive manufacturing (AM) and smart materials, has advanced the field of soft robotics. However, there are currently lack of methods or tools that capable of aiding in the generative design of 4D AM structures. The current generative design procedure for 4D AM structures often lacks transferability among various structures due to limited understanding of shape memory material behaviors for soft robotics. To develop such a digital library, investigation of fundamental elements, such as material properties of shape memory materials, geometry parameters of design primitives, and… More >

Abstract In this study two novel forms of textile-assisted direct ink writing (DIW) of room temperature vulcanised (RTV) silicones were explored: Silicone DIW on spandex fabric, and Silicone DIW on dissolvable fabrics. These processes were evaluated by incorporating resulting components into 4 soft robotic devices: impact resistant elbow pads, a soft passive suction cup gripper, and two fiber embedded inflatable tendril-like soft grippers.

Abstract Arthritis, caused by degeneration and wear of articular cartilage, affects millions of patients worldwide. It can result in chronic pain, swelling, stiffness, and significantly affect the mobility of patients. Hence, identifying a material as an artificial alternative to replace damaged cartilage is of great benefit. Hydrogel, because of its high water content and similarity with the extracellular matrix of cartilage, has been explored for potential use as artificial cartilage. In this investigation, Polyvinyl Alcohol-Polyethylene Oxide (PVA/PEG) hydrogel with similar mechanical properties to human articular cartilage (e.g. compressive modulus, stress-strain response) was fabricated using a freeze-thaw… More >

Abstract This study introduces an innovative plug-in developed within the ABAQUS and Fox GUI environments, which is designed to streamline the design and simulation of hybrid composite laminates for ballistic impact resistance. The plug-in provides an advanced, user-friendly interface for composite laminate design, projectile selection, and ballistic impact simulation parameter configurations. It includes accurately reconstructed models of three projectile types: the tungsten-carbide core projectile M993, the hardened steel core projectile M61, and the lead-core projectile M80, based on scanned data. A distinctive feature of the plug-in is its capacity to facilitate the design of hybrid composite… More >

Abstract Thermoplastic polyurethane (TPU) offers a superior impact and perforation resistance. This paper presents a study on manufacturing a range of hybrid laminated structures made of TPU, glass fibre reinforced plastic (GFRP), styrene-butadiene rubber (SBR) and metal mesh materials, and further on investigating the structural response of the TPU based composite sandwich laminated structures. These laminated structures were tested under quasi-static perforation and low velocity impact loading to determine their structural responses and energy absorption characteristics. It has been shown that three-layer and five-layer laminates with lay-ups of GFRP-TPU-GFRP or TPU-GFRP-TPU and GFRP-TPU-GFRP-TPU-GFRP or TPU-GFRP-TPU-GFRP-TPU subjected… More >
