The machine utilizes a torsional shear method, with a rotational shearing action applied continuously until a constant residual strength value is obtained. The use of a ring shear machine provides several benefits, including the maintenance of a consistent cross-sectional area of the shear plane during the test. The ring shear testing conducted herein is used to further investigate the sources of strength loss for GMX/NGT interfaces from peak to the residual strength because the residual strength develops . A torsional‐ring‐shear apparatus and test procedure are described for measuring soil/geosynthetic and geosynthetic/geosynthetic interface strengths.

torsional ring test

Principle of rotational shear testers: a. torsional shear tester; b. ring shear tester In contrast to a torsional shear tester, the shear cell of the ring shear tester is annular-shaped like a ring (Fig. 4.2.b). Thus the deformation of the bulk solid specimen is more homogeneous, but still dependent on . Previous studies on the hollow cylinder torsional shear test (HCTST) have mainly focused on the macroscopic behavior, while the micromechanical responses in soil specimens with shaped particles have rarely been investigated. This paper develops a numerical model of the HCTST using the discrete element method (DEM). The method of bonded spheres .

To develop the correlations, torsional ring shear tests are being run on diverse, fine-grained samples with plasticity indices greater than 10 from across the country and world. The torsional ring shear test was chosen to measure residual shear strength because it can apply shear displacement infinitely in a single direction and failure plane.1.1 This test method provides a procedure for performing a torsional ring shear test under a drained condition to determine the residual shear strength of cohesive soils. An undisturbed specimen can be used for testing.the Standard Test Method for Torsional Ring Shear Test to Determine Drained Residual Shear Strength of Cohe-sive Soils (ASTM D 6467-99). The clay was processed as described above before testing. To begin each test, the processed clay was spread in the Fig. 2: Bromhead ring shear apparatus. Bromhead ring shear specimen container using a spatula. 1.1 This test method provides a procedure for performing a torsional ring shear test under a drained condition to determine the residual shear strength of cohesive soils. An intact specimen can be used for testing. However, obtaining a natural slip surface specimen, determining the direction of field shearing, and trimming and aligning the usually non .

1.1 This test method provides a procedure for performing a torsional ring shear test under a drained condition to determine the fully softened shear strength and nonlinear strength envelope of cohesive soils. The fully softened strength is used to evaluate the stability of slopes that do not have a preexisting shear surface.Features. Fully automatic standalone ring shear soil testing system for performing torsional ring shear test in drained condition to determine the residual shear strength of cohesive soil.; Managed by local user interface with 6” touch screen high resolution color display Environmentally friendly and quiet with brand new Electromechanical Servoactuation (EmS) technology 1.1 This test method provides a procedure for performing a torsional ring shear test under a drained condition to measure the fully softened shear strength and stress dependent strength envelope of fine-grained soils (using a reconstituted normally consolidated specimen). The fully softened strength and the corresponding stress dependent .

However, obtaining a natural slip surface specimen, determining the direction of field shearing, and trimming and aligning the .test with a modified torsional ring shear machine was developed in laboratory, which can simulate the creeping landslide phenomena. To understand the creeping behavior of landslide soils, three

This test method provides a procedure for performing a torsional ring shear test under a drained condition to determine the residual shear strength of fine-grained soils. This test method is performed by shearing a reconstituted, overconsolidated, presheared specimen at a controlled displacement rate until the constant drained shear resistance .

Standard Test Method for Torsional Ring Shear Test to Determine Drained Residual Shear Strength of Cohesive Soils1 This standard is issued under the ﬁxed designation D 6467; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

In this study, a new stacked-ring torsional shear apparatus was developed to study the multiple liquefaction test of saturated Toyoura sand. 3D clumped DEM simulation were also performed to study the fabric evolution of the soil during the multiple liquefaction process.

Torsional ring shear tests were conducted to investigate Soil/Geosynthetic Interface Strengths of various geomembranes. A selection of seven smooth and three textured geomembranes (10 total) that can be factory fabricated were sheared against two soils to investigate the range of soil/geosynthetic interface strengths. 1.2 This test method provides a procedure for performing a torsional ring shear test under a drained condition to determine the residual shear strength of fine-grained soils. This test method is performed by shearing a reconstituted, overconsolidated, presheared specimen at a controlled displacement rate until the constant drained shear .The data presented herein show that using a clogged or unsaturated porous disc will require a drained shear displacement rate that is one to two orders of magnitude slower than required, e.g., 0.018 mm/min, if the porous discs are clean, maintained, and saturated as recommended by the original equipment manufacturer and the ASTM D7608, Standard .Torsional shear stress solved examples: 1] The shaft of the motor is rotating with a maximum torque of 6 N.m. If the shaft has a diameter of 25 mm, find the maximum shear stress acting onto the shaft.

procedures, describes the torsional-ring-shear apparatus and test procedure used to measure interface strengths of various soil/geosynthetic and geo- synthetic/geosynthetic interfaces, presents some typical ring-shear test re- sults, and illustrates the relevancy of ring-shear interface-strengths using theTorsion tests twist a material or test component to a specified degree, with a specified force, or until the material fails in torsion. The twisting force of a torsion test is applied to the test sample by anchoring one end so that it cannot move or rotate and applying a moment to the other end so that the sample is rotated about its axis.
