Descripción: “...The results showed that the frictional resistance increases proportionally to the angulation of the wire, but at the same time, this frictional resistance strongly depended on the geometry of the slot and the Young´s modulus of the bracket and the wire. . ...”

Descripción: “...This study presents graphs of the variation of shear strength, cohesion, and friction angle versus speed and their impact on design, as well as conclusions and recommendations. ...”

Descripción: “...The variation of the speed versus shear strength of the undrained shear strength was evaluated by conducting direct shear tests on undisturbed samples under Unconsolidated and Undrained conditions, soil samples were recovered using shelby thin-walled tubes, graphs of the variation of the shear strength, cohesion and friction angle versus speed and their impact on design. ...”

Descripción: “...The residual strength does not depend on the size of the shear box and particle size 3. Peak friction angle is underestimated when calculated with the contour measures compared with those obtained in the cutting zone.ResumoOs resultados do ensaio de cisalhamento direto tanto experimental como em simulações com elementos discretos se vem afetados pela escala, ou seja, os resultados dependem do tamanho das partículas e da caixa do cortador. ...”

Descripción: “...Additionally, the Monte Carlo method was also simulated using a lognormal distribution to model cohesion, in a more coherent manner with the actual statistical behavior of that variable, while the friction angle remained modeled by a Gaussian distribution. ...”
