In this study, junction strength, stress distribution of geogrids and wide-width tensile behaviors were interpreted by Visual FEA/Edu program as finite element analysis. Through comparison to test values, it is examined whether the validity of prediction values by Visual FEA/Edu program was reasonable or not. For stress distribution effect of cross machine direction ribs, warp knitted type showed better than woven type. Through contour image from the results of finite element analysis, the stress change in adjacent point around the ribs could be predicted. For analysis of tensile behaviors, prediction data of finite element analysis is dependent on the tensile test data and how to devide elements and consist the finite element network of geogrids.
