THE USE OF FINITES ELEMENT METHOD (F.E.M.) IN THE STUDY OF THE GEOSYNTHETICS MATERIALS.
The study of stress x strian relation by F.E.M. models is very important to improve and understand dispersives strenghts behaviors in non-woven samples.
This article enphatizes the right filosophy that using the methodology of Finite Element Method (F.E.M.) to measure the behavior of the geotextile materials under large and little deformations. Although F.E.M. have been used initially in structurals applications, as the linear structural analysis, free and forced vibrations, the non-linear analysis envolving large deformations, plasticity and structural instability. The discretization technics of continuous systems that have obtained success in the ambit of the structural analysis can be applied to the other areas of engineering. There are more areas that F.E.M. is applied such as mathematical and physics systems. In the geothecnical science, F.E.M. is applied in many areas as flows law’s, dams behaviors and others.
Thus, F.E.M. is a important and approximate method that calcule continuous systems where a body is divided in a finits number of parts (elements) connected to many discrets points, called of nodes. Your application of geothecnical areas, specificated in the geossynthetics, is so briefly, used principally to measure the geotextile behaviors on the strength functions. The complete paper will be send to the Geotechnical Engineering Jounal in 2008.
