Computer-aided analysis of the forging process
Matjaž Šraml, Janez Stupan, Iztok Potrč, Janez Kramberger, 2004, original scientific article

Abstract: This paper presents computer simulation of the forging process using the finite volume method (FVM). The process of forging is highly non-linear, where both large deformations and continuously changing boundary conditions occur. In most practical cases, the initial billet shape is relatively simple, but the final shape of the end product is often geometrically complex, to the extent that it is commonly obtained using multiple forming stages. Examples of the numerical simulation of the forged pieces provided were created using Msc/SuperForge computer code. The main results of the analysis are deformed shape, temperature, pressure, effective plastic strain, effective stress and forces acting on the die.

Agricultural-industrial integration and new applications of natural fibres
Ana Maria de Bicalho, 2009, original scientific article

Abstract: In recent years natural fibre production has taken on considerable appeal because of new industrial applications in environmental friendly products and growing demand for fibres could contribute to social welfare of poor farmers in developing countries. The new uses of natural fibres are part of highly technical green solutions for problems in the industrial and consumption regions but it may be asked whether this demand really addresses social and ecological issues in regions of primary production. These issues are examined in the Brazilian Amazon where recently a composite fibre sheet factory was opened and fibre cropping is making a comeback after decades of economic stagnation. It is shown here that the expansion of the activity, while significant, has not yet reached the scale of the past, but the market is promising, particularly in the automotive industry, which could further stimulate jute and malva production in the region.
Keywords: natural fibres, new industrial applications, agricultural-industrial integration, Amazon region, Brazil
