For Geocells strength test
1,tensile shear test
2, peeling test,
3, splitting test
4, Local overstressing Test
A geocell junction can fail in four different ways:
1) by shear : when failure is caused by a force parallel to the junction itself;
2) by peeling or delamination : when failure is caused by a force, normal to the junction, which separates the cells from each other at one edge of the junction;
3) by splitting: when a force, normal to the junction, pulls away the two cells adjacent to the junction;
4) by local overstressing: when the fixation element locally overstresses the junction, leading to a compression, shear or peel failure.
