“…In addition, it was determined that the tensile stiffness and maximum tensile strength of PP and HDPE geogrids increased with the rate of change. Gao, Zhang, et al 29 conducted tensile tests on geogrids made of four materials (PLA (polylactic acid), PLA/CF (carbon fiber reinforced polylactic acid), TPU (thermoplastic polyurethanes), and fiberglass). The results showed that the tensile strength of PLA/FAC and PLA geogrids decreased with increasing temperature, while the glass fibre and TPU geogrids increased with increasing temperature.…”

Following the emergence of new morphology geogrids, tensile tests on some of the new morphology geogrids were conducted in this paper for practical engineering options. The study focuses on the tensile testing of 3D printed geogrids to analyze the effects of morphology differences (material, planar structure, filling rate, rib width and rib height) on the tensile properties of geogrids. The test results show that the tensile properties of high density polyethylene geogrids are stronger than those of polylactic acid geogrids. Increasing the filling rate of geogrid can increase the tensile performance while decreasing the rate of tensile performance improvement. In contrast to the elongation at the break of the geogrid, the maximum tensile strength and the maximum tensile modulus increase in the order of bidirectional, triaxial and quadaxial geogrids. When the rib width and the rib height increase by the same amount, the rib height increases the maximum tensile strength of the geogrid more than that of the rib width.

The investigation of cyclic shear response on a geosynthetic–soil interface is important for reinforced soil structures. A stereoscopic geogrid with a thickened transverse-rib thickness increases the interaction with the soil compared with a planar geogrid. In this study, three-dimensional printing technology was used to produce stereoscopic geogrids with transverse-rib thicknesses of 5, 10, 15, and 20 mm. The influences of different cyclic shear displacement amplitudes (1, 3, 6, and 10 mm) and normal stresses (20, 40, and 60 kPa) on the direct shear tests under static and cyclic loading at the stereoscopic geogrid–sand interface were investigated. The results indicate that the maximum shear stress can be improved by the stereoscopic geogrid at larger cyclic shear displacement amplitudes. The effect of transverse-rib thickness on the fitted curves of the normalized interface shear stiffness and damping ratio was reversed. The cyclic shear process altered the relationship between apparent cohesiveness and transverse-rib thickness. The peak stress ratio of the stereoscopic geogrid–sand interface is proposed as a function of the transverse-rib thickness and maximum dilation angle.
