Cavitation instabilities in plastics and rubber-modified plastics
Spherical void expansion in plastics and rubber-modified plastics is investigated under radial traction conditions. The plastics are modeled as elastic-plastic pressure-sensitive materials and the rubbers are modeled as nonlinearly elastic materials. First, the growth of a spherical void in an infinite plastic matrix is investigated under remote radial traction conditions. The results show that...
متن کاملBiodegradability of Plastics
Plastic is a broad name given to different polymers with high molecular weight, which can be degraded by various processes. However, considering their abundance in the environment and their specificity in attacking plastics, biodegradation of plastics by microorganisms and enzymes seems to be the most effective process. When plastics are used as substrates for microorganisms, evaluation of thei...
متن کاملThe Problems with Plastics
Plastics in the pharmaceutical industry are as ubiquitous as endotoxins. From solution containers to medical devices, plastics are not just commonplace. they are often the best material for the application. Because plastics are formed at very high temperatures that easily destroy endotoxins, plastics should be expected to be endotoxin-free. Unfortunately, the often excessive and usually uncontr...
متن کاملRoutes to greener plastics
How to hide a dimension from view Compacted dimensions are essential ingredients of advanced string theories; the extra dimensions used to describe the world are hidden from view, or compacted. Pendry et al. used concepts of transformation optics, in which metamaterials are designed to produce specific optical properties, to show theoretically that compacted dimensions could be possible in plas...
