Textiles usually exhibit much larger resistance to in-plane deformation than to bending deformation. However, the latter essentially determines the formation of folds and wrinkles which in turn govern the overall appearance of the cloth. The resulting numerical problem is inherently stiff and hence susceptible to instability. This overview is devoted to a closer investigation of bending deforma...

In this paper, the laser bending process of a circular tube made of mild steel has been investigated experimentally. For this purpose, the effects of the irradiating length and the number of irradiating passes on the main bending angle of a laser bent tube are studied. In addition, the main defects of the laser tube bending process such as lateral bending angle, ovality and thickness variation ...

The cilia and flagella of eukaryotic cells function by active bending that produces cell movements and fluid flows in their environment. They contain a common cytoskeleton, known as the axoneme, that is the locus of all the enzymes and mechanical components that are required for production of useful bending. The bending of many flagella, and some cilia, is planar, or at least nearly planar. In ...

With the escalating demands for downsizing and functionalizing mobile electronics, flexible electronics have become an important aspect of future technologies. To address limitations concerning junction deformation, we developed a new connection method using a film-type connector that is less than 0.1 mm thick. The film-type connector is composed of an organic film substrate, a UV-curable adhes...

We investigate 3-dimensional flagellar swimming in a fluid with a sparse network of stationary obstacles or fibers. The Brinkman equation is used to model the average fluid flow where a flow dependent term, including a resistance parameter that is inversely proportional to the permeability, models the resistive effects of the fibers on the fluid. To solve for the local linear and angular veloci...

Fracture toughness resistance curves describe a material's resistance against crack propagation. These curves are often used to characterize biomaterials like bone, nacre or dentin as these materials commonly exhibit a pronounced increase in fracture toughness with crack extension due to co-acting mechanisms such as crack bridging, crack deflection and microcracking. The knowledge of appropriat...

This study reports the latest research into alpaca and wool fibres. In particular, those properties that have received little attention in research literature have been examined. They include single fibre abrasion and bending fatigue, single fibre tensile properties, as well as resistance to compression behaviour. These properties are important because they affect the softness and pilling prope...
