Investigation of rheological properties of graphene oxide and its nanocomposite with polyvinyl alcohol

Abstract. This paper focuses on the rheological properties of graphene oxide (GO) and its nanocomposite with polyvinyl alcohol (PVA). The purpose of this paper is to compare the mechanical properties of these materials. GO is a nanomaterial that has been widely studied in engineering. The comparison of its rheological properties with those of its nanocomposite with PVA has been required. Rheology is an appropriate method for the comparative investigation of the mechancial behavior of these materials.

Using Autodesk software in University learning process

An integral part of mechanical engineer workplace is a personal computer with specialized software, including CAD, which allows automating the work of engineering and technological preparation of production. One of the largest suppliers of CAD for mechanical engineering is a multinational company Autodesk. Therefore, for the students – future mechanical engineers – the ability to work with this company’s software is the key to their demand in the labor market.
