Studying the effect of roughness on soil-geotextile interaction in direct shear test
Abstract One of the methods of increasing soil resistance against failure is soil reinforcement using geosynthetics. Soil-geosynthetic interactions are of great importance and are affected by friction and adhesion at their interface. Soil gradation, contact surface roughness and geotextile density are among the factors affecting soil-geotextiles interaction this study, to investigate the eff...
متن کاملBall Indentation on Cohesive Powder Beds
13 In the shear deformation of powder beds beyond the quasi-static regime the shear stress is dependent 14 on the strain rate. Extensive work has been reported on the rapid chute flow of large granules but the 15 intermediate regime has not been widely addressed particularly in the case of cohesive powders. 16 However in industrial powder processes the powder flow is often in the intermediate r...
متن کاملNumerical Discrete Element Simulation Of Soil Direct Shear Test
One of the most common methods to measure soil mechanical properties (namely cohesion and internal friction angle) is direct shear box test. In this paper the development of a three-dimensional (3D) discrete element soil model for simulation of a cohesive soil’s direct shear test is presented. The aim was to calibrate the properties of the Hertz-Mindlin with bonding contact model available in E...
متن کاملParticle Size Effect on Shear Strength of Granular Materials in Direct Shear Test
The effect of particle size on shear strength of granular materials are investigated using direct shear tests. Small direct shear test (60 mm by 60 mm by 24 mm deep) were conducted for particles passing the sieves with opening size of 2.36 mm. Meanwhile, particles passing the standard 20 mm sieves were tested using large direct shear test (300 mm by 300 mm by 200 mm deep). The large direct shea...
متن کاملDiscrete-continuum Analysis of Shear Banding in the Direct Shear Test
The direct shear test is a widely used method of determining peak and critical state strength parameters for soil and for soil-manufactured material interfaces. However, stress conditions inside the box during shear are not well known. This paper presents a new micromechanics-based approach that modifies existing relationships between plane strain and direct shear friction angles taking into ac...
