[1] Convection may occur in the ice shells of satellites in the outer solar system. The style of convection, rate of heat transport, and resulting surface features depend on the rheology of ice, which in turn depends on temperature, grain size, stress, and crystallographic preferred orientation (CPO). Here we study the effect of CPO development and anisotropic viscosity on convection by couplin...

RIFT (Resin Infusion under Flexible Tool) process modelling requires accurate material data like resin viscosity, reinforcement compressibility and reinforcement permeability. During the mould closing, the compression phase and the resin flow are important stages that strongly influence the quality of the obtained parts. In RIFT process the upper mould is a formable vacuum bag: its flexibility ...

This Keynote Paper is concerned with the fundamental mechanics of granular materials with a particular reference to non-coaxial behaviour. The non-coaxial behaviour refers to the non-coincidence of principal stress directions and corresponding principal plastic strain rate directions during plastic deformation. At present, the majority of soil models used in geotechnical practice are those of a...

Fabric quality and durability are a concern with fibers that contain natural antibacterial properties or are treated to provide antibacterial properties. The textile industry has developed antibacterial fabric to address the public’s desire for improved sanitation and personal protection against disease transmission. The approach has been to attach biocidal or some bacteriostatic groups to the ...

Surface flattening plays an important role in the whole process of garment design. We proposed a novel method by using three-dimensional triangle mesh this study. First, is flattened to two-dimensional plane approximate original surface. The initial results are then used as preliminary guesses for subsequent optimizations. Considering that deformation energy real woven fabric related tensile or...

Current shielding effectiveness (SE) of electromagnetic shielding (EMS) fabric is tested in the plane state, the testing results are difficult to describe the shielding effect of a garment in a curve surface state after manufactured by the fabric. To solve this problem, this study proposes a new SE computation model of the EMS fabric based on a SE vector. The model can calculate a theoretical S...

Here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (TEA) and zinc acetate. The ZnO nano particles (NPs) were formed and stabilized on the fabric surface by amine compound at 130 °C for 1 h. The synthesis of nano ZnO particles on the polyester fabric were confirmed by X-ray diffraction (XRD) pattern...
