“…The hand-held shear vane (Figure S1A) was designed for soft homogenous clays (Jafari et al, 2019) and records the axial strength of the top layer of the test material to a depth dependent on the length of the blade (He et al, 2018). After insertion into the cohesive material, the blade is rotated at a constant angular speed until the material fails.…”

“…The undrained shear strength can then be directly extracted based on the torque and dimensions of the shear vane. For each sample, 6-12 tests were conducted to characterize the spatial variability of shear strength, assuming that the material penetrated by the vanes was homogeneous and isotropic (He et al, 2018). For our field analysis, we tested 3 different shear vane devices across a range of sediments and sedimentary rocks, exploring the repeatability of each device and honing our techniques.…”

“…The vane shear test (VST) is a common method for measuring the undrained shear strength of clay in geotechnical engineering applications, such as pile capacity and slope stability [7][8][9][10][11]. With the expansion of offshore oil exploration in the past few decades, the VST has been widely applied in offshore engineering to measure the strength of marine sediments [12][13][14][15][16][17].…”

The laboratory miniature vane shear test (MVST) has been widely used to measure the undrained shear strength of marine sediments in offshore engineering. However, the transfer of the soil sample in tube samplers from the seabed to the laboratory releases the in situ confining stress acting on the soil and will decrease the soil strength. In this research, in order to investigate the effects of confining stress on the undrained shear strength of marine sediments, the Coupled Eulerian-Lagrangian (CEL) approach in ABAQUS is used to model the three-dimensional standard and miniature vane shear tests to estimate the undrained shear strength of sensitive clay with different sensitivities under various stress conditions. Based on the numerical simulation results, a linear strength model that not only considers confining stress effects but also can eliminate the size effects caused by vane blades of MVST is proposed. The proposed model can be used to estimate the undrained shear strength of the sensitive clay under shallow seabed surfaces.

“…The main goal of the present work is to develop an in situ measurement which is utilized for the calibration of discrete element micromechanical parameters of the undisturbed soil. Vane shear test (He et al , 2018) seemed to be an adequate tool for doing such in situ measurements. The only problem with the original form of this test, that there is no vertical load applied during testing, and because of this the “failure curve” cannot be created as in case of standard shear test.…”

PurposeTransportation of the measurement samples from their original place to the measurement site causes significant changes in their mechanical properties. The possibility of making in situ measurements helps to create more precise discrete element models.Design/methodology/approachThe possibility of using in situ modified vane shear test based measurement for the calibration of discrete element models is demonstrated in this work.FindingsThe advantage of employing the adjusted vane test is that the values of in situ measurements can be used for the calibration.Originality/valueThe procedure we present allows us to perform accurate discrete element calibration using data from on-site measurements that can be performed quickly and easily.
