Effect of Shearing Strain-Rate on the Undrained Strength of Clay

Source

Dynamic testing method is required to determine the strength of soils for problems of dynamic loading. This paper presents an experimental technique for measuring the relationship of undrained shear strength and strain-rate of a clay. Torsion tests were performed on remolded hollow cylinder specimens. The test results show that the undrained shear strength increases initially with strain-rate from the static undrained strength, but subsequently the undrained strength reaches an ultimate value as the strain-rate increases.
