... by manufacturers cannot be used directly because their charts are developed by applying fluid pressure, but when sand is used as contact material, EPCs’ response changes significantly. The major factor that causes deviation of EPC response in fluid and sand is that in fluid calibration, the applied load is fully...

... of the measurement from the DIC technique depends on the position of the camera and light panels, the color temperature of light, size of the region of interest (RoI), type and relative density of sand, seeding ratio, type of camera, and strain rate used in experiments. In the paper, the effect of above-mentioned...

...Bruma Souza; Ryan van der Heijden; Jean Benoît ABSTRACT Recycled geosynthetic materials can be incorporated into sand-based soils to improve their shear characteristics and enhance surface response in different engineering applications. This paper summarizes research undertaken to explore...

...Xin Zhang; Mingliang Liu; Tong Jiang ABSTRACT An experimental study on sand deformation around two-plate anchors connected to one shaft was conducted by using the digital image correlation technique to investigate load–displacement response and deformation fields in various embedment depth, plate...

... on top of the specimen to minimize the effect of compliance and component friction on load measurements. The I-mcDSS device tests cylindrical specimens confined using either a wire-reinforced membrane or stacked rings. Experiments conducted on a uniformly graded Ottawa sand are presented to illustrate...

...) to obtain angular distributions of V S . Specimens of glass beads and angular natural sands were tested in isotropic and one-dimensional (1D) compression to demonstrate the results obtained with the multi-BE system. The experimental results indicate that the effects of fabric and stress anisotropy can...

...Andrea Ventola; Roman D. Hryciw ABSTRACT Sed360 is a largely automated system for determining image-based particle size distributions (PSDs) of sands. A sedimented soil specimen contained in a 25.4-mm (1-in)-diameter circular acrylic tube sits atop a rotating stage. While the tube rotates, a camera...

... that was adopted in the literature in modeling soil-structure interaction between basement walls and sand backfill. Unique results from the cyclic tests indicated a process of densification that dominated the volumetric tendency of the sand during cyclic loading, with the p-y curves showing a significant increase...

...Belinda Anna-Maria Bock; Friedrich Levin; Stefan Vogt; Roberto Cudmani ABSTRACT Creep of sand is a consequence of micromechanical processes within the granular soil skeleton. These processes are known sources of acoustic emissions. Therefore, acoustic emission analysis provides additional...

...Joon Han Kim; Scott M. Olson ABSTRACT Earthquake-induced free-field settlement of coarse-grained soils has historically been assessed using laboratory element tests under drained or undrained conditions. However, in saturated sands, dynamic centrifuge and 1 g shaking table tests illustrate...

... in sand subjected to various cyclic tensile loads. The suction bucket was installed via negative differential pressure (suction). The results show a strong effect of the applied load magnitude on the evolution of displacement, plug heave, and suction induced. Greater displacement accumulation is observed...

... water was used as a doping agent to saturate a column of sand as a test sample. The article focuses on how the technique was employed to image a column of sand as the degree of saturation changes. Water and air were separated easily, and the degree of saturation was calculated for the sand column...

...Linzhu Li; Magued Iskander This study investigates the efficacy of dynamic image analysis (DIA) for determining particle size and shape distribution. The method employs a high-frame-rate camera to image individual particles of sand that have been transported and separated using a stream...

... potential detrimental impacts of current standards, the article describes a case where sand was planned to be used as a filter layer for a solid waste project. Large quantities of sand had been delivered at the construction site. The K sat value of the sand, as compacted, had to exceed 10 −4 m/s to satisfy...

The assessment is performed by comparing volumetric strain determinations using an external volume...

... of the oldest methods to obtain the desired unit weight throughout the testing tank is by dropping the sand from a predetermined height. This method often suffers from particle segregation, which reflects on the test results. Applying compaction effort on the surface of the soil is another method for soil...
