This article summarizes current rock triaxial test systems, which cannot concurrently solve the problems of subzero temperatures, creep, disturbance, and high sampling rates. Based on existing...

...K. Hashiba; K. Fukui A creep test is a helpful method for investigating the long-term deformation of rock. However, most previous creep tests on rock were carried out for less than a few weeks, and only a handful were performed for longer time periods. This article reports an ongoing long-term...

... tensile loads were applied to the geogrid incrementally using a pullout device. The confining pressure increased the soil-geogrid interface friction force and thus affected strain distribution along the geogrid length. Creep developed in the geogrid as the applied tensile load increased. The geogrid creep...
