Geotextiles, which are the members of geosynthetics, are gaining more importance in complex applications such as construction sites and agricultural areas by virtue of their various advantages. Geotextiles are exposed to various loads in their application areas so that the knowledge of their mechanical behavior is a required parameter. In this study, a geometrical model was constructed by using theory of layered composite materials to predict the nonwoven geotextiles mechanical properties. Stress analysis of model was performed in commercial finite element software. Mechanical properties of fibers and constructional parameters of fabrics were used as data in the analysis. The comparison of theoretical and experimental results indicated that, meaningful stress data can be obtained from the stress distribution of computed models. However, it was found that, the difference between computed and measured elongation values was high. Consequently, it can be said that the model can be used as a tool to ease the selection of raw material and product type, and thus it will provide an advantage to the manufacturers in terms of cost and duration of design and production processes.
