...W. Kongkitkul; F. Tatsuoka; D. Hirakawa The viscous property of polymer geosynthetic reinforcement, which causes creep deformation, is first summarised. The creep deformation and associated creep rupture characteristics, when subjected to long-term sustained loading under the following three...

...D. Hirakawa; W. Kongkitkul; F. Tatsuoka; T. Uchimura A series of conventional and unconventional tensile tests were performed on six types of geosynthetic reinforcement to evaluate their viscous properties. It is shown that the isochronous model, according to which the load (or the stress...
