Abstract (en)
In order to provide more efficient production and use of geotextile
materials, their structural and mechanical properties, and then elastic limits
of geotextile were defined, and a rheological model which can be used for
the prediction of the behavior of geotextiles during exploitation was
developed. Based on the obtained results, the limits of the elastic
deformation of needled geotextile materials which define the permitted load
that geotextile materials can be subjected to without disturbing their
structure were determined. Also, the interconnectivity of parameters of the
limit of elastic deformations with the parameters on the breaking limit of
geotextile materials was analyzed. The elongation of geotextile made from
regular polyester, recycled polyester and polypropylene fibers is described
by differential equations that are based on mechanical models. Rheological
model will contribute to the development of the methods for the prediction
of mechanical properties of needled geotextile materials according to their
use. In this way the technical preparation of the production is simplified and
improved, and the conditions for the exclusion of the test series are fulfilled,
which contributes to energy and raw materials savings.

“Data exchange” service offers individual users metadata transfer in several different formats. Citation formats are offered for transfers in texts as for the transfer into internet pages. Citation formats include permanent links that guarantee access to cited sources. For use are commonly structured metadata schemes : Dublin Core xml and ETUB-MS xml, local adaptation of international ETD-MS scheme intended for use in academic documents.
