“…The values of TRR and SR for all the PSC tests on reinforced sand specimens performed in the present study are listed in Tables 2 and 3, respectively. Note that the values of J 5z, PVA GG and˜R max (unreinforced sand) obtained by the present study are very similar to the respective ones with the similar dimensions of specimen reported by Peng et al (2000). The TRR and SR values of the respective reinforced sand specimens from the present study are plotted in Fig.…”

“…It should be noted that, in the present study, PSC tests on relatively large sand specimens (230 mm-wide, 243 mm-deep in the plane strain direction and 570 mm-high) were performed to accommodate several prototypes of geosynthetic reinforcement as used in full-scaleˆeld projects. This type of experimental study has not been found in the literature other than those by the authors and their colleagues (Hirakawa et al, 1998;Peng et al, 2000;Kanemaru et al, 2006;and Kongkitkul et al, 2006a, b) to the best of the authors' knowledge.…”

“…A number of PSC tests were also performed to evaluate the eŠects of stiŠness, surface roughness and covering ratio (CR) of reinforcement on the strength and deformation characteristics of reinforced soil under plane strain conditions (e.g., Tatsuoka and Yamauchi, 1986;Ling and Tatsuoka, 1994;Peng et al, 2000). Similar drained PSC tests were performed on reinforced sand in the present study to evaluate the residual deformation by sustained and cyclic loading.…”

To evaluate the eŠects of reinforcement type in terms of stiŠness, viscous property, rupture strength, shape and loading history on the stress-strain behaviour during primary, sustained and cyclic loading of reinforced sand, a series of drained plane strain compression tests were performed on Toyoura sand. The sand specimens were reinforced with two types of polymer geogrid as well as two types of metal grid, having largely diŠerent stiŠness values and surface conditions. Despite that the eŠects of reinforcement type on the overall stress-strain characteristics of reinforced sand and their rate-dependency are signiˆcant during primary loading, the eŠects are much smaller than the diŠerence in the stiŠness of reinforcement. The eŠects of reinforcement type on the global unloading behaviour and the residual strain by cyclic loading during otherwise global unloading are generally insigniˆcant or negligible. The residual strains by cyclic loading of reinforced sand became substantially small by preloading as well as pre-sustained loading and precyclic loading at higher load levels. With this procedure, polymer geosynthetic reinforcement, which is much more extensible and viscous than metal reinforcement, can be used to reinforce soil structures allowing very limited residual deformation.

Cellular solids like this are used in wire mesh in box gabions 13) , in geogrid for reinforcement of geomaterials 14) and so on. The square cell is known to exhibit strong anisotropy and a Poisson ratio at 45 degree to the axis of approximately 1.…”

The development of a nonlinear homogenization for media having lattice-like periodic microstructure is presented. For continuum media, conventional homogenization methods lead to classical continuum boundary value problems at both micro-and micro-scales. However, discretizing latticelike micro-structures, such as cellular solids, by frame elements is a natural step. The main difficulty in applying frame elements to micro-scale problems is inconsistencies between the kinematic field of the frame elements and the micro-scale displacement field. Numerical examples of cellular solids demonstrate the feasibility and strengths of the computational efficiency of the method presented.
