Experimental quantification of anisotropy in fabric

Waves are an engineer’s best friends or the worst enemies The purpose of this study is to develop and verify an indirect measure of coarse-grained soil fabric using shear wave velocities ($V_s$) for materials with different particle shapes. $V_s$ is obtained by a novel multi-bender element system which consists of five pairs of bender elements, with each pair capturing the shear wave velocity in a specific orientation along the specimen.

Quantification of anisotropy in fabric using numerical techniques

Granular materials like sandy and gravely soils are composed of an assembly of individual particles. A given soil deposit or specimen has a specific arrangement of individual particles, clumps of particles, and void spaces. This spatial arrangement, along with the orientation of interparticle contacts, encompasses the basis of the soil fabric concept. Experimentally soil, fabric can be quantified by non-destructive methods such as image microscopy and X-ray computed tomography. While these state-of-the-art methods provide accurate and useful information, they require specialized equipment and analysis methods.
