...Dat G. Phan; Giang D. Nguyen; Ha H. Bui; Murat Karakus; Yosuke Higo Localised failure and the appearance of a localisation band are common in triaxial tests on soils, including partially saturated soils. In a classical analysis, stress–strain and suction–saturation degree in the post-localisation...

..., the stress required to cause liquefaction is calculated and compared to the characteristic earthquake-induced stress. If found to be lower, the examined deposit is deemed susceptible to liquefaction at the examined depth. where f exp represents the frequency of loading in the triaxial tests...

...Georgios Birmpilis; Edward Andò; Olga Stamati; Stephen A. Hall; Eleni Gerolymatou; Jelke Dijkstra Unique four-dimensional (4D) deformation data are collected during drained triaxial tests on intact specimens of a natural sensitive clay. This requires the development of a miniature triaxial cell...

...J. W. Pappin; S. F. Brown; M. P. O'Reilly The results of triaxial tests on specimens of compacted crushed rock in dry, saturated and partially saturated states are presented. A resilient strain model, developed earlier for dry materials, is shown successfully to predict strains in saturated...

... that the critical state friction angle in sands may be a function of the critical state void ratio. The steady/critical state line is shown to be non-linear, and to have a marked increase in slope at stress levels greater than about 1000 kPa. The critical or steady state point must be selected from triaxial test...
