Abstract:The high degree of heterogeneity in fabric composite materials is identified as a major problem in their structural analysis. A procedure is proposed to represent the material stiffness variation as a function of the spatial coordinates by using splines. The stiffness variations are exemplified using a plain weave composite. The role of this stiffness function is to facilitate the calculation of the averaged material stiffness tensor for arbitrary domains in the form of finite elements. Once this exercise has … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
