Direct shear test graph
Web1 day ago · During the cutting simulation process of the following five groups, when the cutting depth exceeds 1 mm, in Fig. 14, the proportion of Type I failure gradually decreases. Among them, three groups of simulated cohesive elements are mainly shear failure, and the granite gradually shows the trend of brittle failure. WebDirect shear test is simple and faster to operate. As thinner specimens are used in shear box, they facilitate drainage of pore water from a saturated sample in less time. This test is also useful to study friction between two materials, one material in lower half of box and another material in the upper half of box.
