Evaluation Method of Granite Multiscale Mechanical Properties Based on Nanoindentation Technology
Geofluids, 2021 In order to study the mechanical properties of granite at the micro- and nanoscale, the load-displacement curve, residual indentation information, and component information of the quartz, feldspar, and mica in granite were obtained using a ...

Soil mechanics surface sampler [PDF]
, 1969 A lunar surface sampler essentially identical to that operated from Surveyor 3 was mounted on Surveyor 7 and performed flawlessly on the moon throughout a range of operating temperatures from +180°F to −167°F.

Comparison between uniaxial and pull-out tests setup for polyester and HDPE geogrids [PDF]
E3S Web of Conferences, 2023 Uniaxial tensile and/or pull-out tests are performed to obtain the stress-strain curve of geogrids. The clamp lining in contact with a specimen in the uniaxial tensile test or the grit of a sandpaper clamp liner in a pull-out test affects the results. In

Rainfall-induced differential settlements of foundations on heterogeneous unsaturated soils [PDF]
, 2013 This study stochastically investigates the rainfall-induced differential settlement of a centrally loaded, rigid strip foundation on an unsaturated soil with spatially varying values of either preconsolidation stress or porosity.

Influence of Rotations on the Critical State of Soil Mechanics [PDF]
, 2010 The ability of grains to rotate can play a crucial role on the collective behavior of granular media. It has been observed in computer simulations that imposing a torque at the contacts modifies the force chains, making support chains less important.

Temperature- and saturation-dependent behaviour of unsaturated clay beams in bending tests [PDF]
E3S Web of Conferences, 2023 The paper investigates the deformation behaviour of partially saturated clay beams under flexural stress. Beams were prepared from two clays and then loaded until failure. Three degrees of saturation and two loading rates were examined for each clay. The

Modelling large deformation problems in unsaturated soils [PDF]
, 2016 Applications of unsaturated soil mechanics often involve large deformations and displacements. This is the case of collapse behaviour of low density soils or the unrestrained swelling of expansive clays.

Perspectives of 3D Probabilistic Subsoil Modeling for BIM
Geotechnics, 2023 Building information modeling (BIM) in the planning and construction of infrastructure projects, such as roads, tunnels, and excavations, requires the generation of comprehensive 3D subsoil models that encompass relevant geological and geotechnical ...
