Abstract: The application of geosynthetics for reinforced earth, also known as mechanically stabilized earth, is gaining popularity in Indonesia. At the same time, many engineers have started using geotechnical finite element software in designing the geosynthetics reinforced earth. Unfortunately, many of them still do not know the importance of elongation factor in determination of the geosynthetics stiffness to be input into the finite element calculation. Some engineers even said that elongation of the geosynthetics need not be considered in selecting the right geosynthetics material, only the breaking strength and the type of geosynthetics need to be considered. Such misconception can lead to bad performance or even failure of the geosynthetics reinforced earth. This paper elaborates the importance of the elongation factor and the correct procedure in determining the stiffness of geosynthetics materials for finite element software input.

Keywords: Elongation, stiffness, geosynthetics, finite element analysis
