시료크기 및 인장속도에 따른 지오그리드의 광폭인장강도 변화특성

The tensile properties of geogrid are affected by such factors as temperature, specimen length, gauge length, testing speed and measuring equipment. The tensile strength of geogrids can be determined by ASTM 06637 and ISO 10319. The main differences between two testing methods are testing speed and specimen length. This paper presents the results of the wide width tensile tests for three geogrids according to different specimen length and tension speed.
