Study of Sericite Quartz Schist Coarse-Grained Soil by Large-Scale Triaxial Shear Tests

Effects of Ballast Degradation on Shear Strength Behavior from Large-scale Triaxial Tests

Ballast, typically comprising large sized aggregate particles with uniform gradation, is an essential layer in the railroad track substructure. Functions of ballast include facilitating load distribution and drainage, maintaining track geometry and track stability, and providing track resilience and noise absorption. Throughout its service life, ballast goes through changes in gradation and par...

Solvent-free coarse-grained lipid model for large-scale simulations.

A coarse-grained molecular model, which consists of a spherical particle and an orientation vector, is proposed to simulate lipid membrane on a large length scale. The solvent is implicitly represented by an effective attractive interaction between particles. A bilayer structure is formed by orientation-dependent (tilt and bending) potentials. In this model, the membrane properties (bending rig...

Effect of Cementation on the Shear Strength of Tehran Gravelly Sand Using Triaxial Tests

Large-Scale Conformational Transitions in Supercoiled DNA Revealed by Coarse-Grained Simulation.

Topological constraints, such as those associated with DNA supercoiling, play an integral role in genomic regulation and organization in living systems. However, physical understanding of the principles that underlie DNA organization at biologically relevant length scales remains a formidable challenge. We develop a coarse-grained simulation approach for predicting equilibrium conformations of ...

Shear modulus and material damping of municipal solid waste based on large-scale cyclic triaxial testing

Representative dynamic properties of municipal solid waste (MSW) are required to perform reliable seismic analyses of MSW landfills. A comprehensive large-scale cyclic triaxial laboratory testing program was performed on MSW retrieved from a landfill in the San Francisco Bay area to evaluate the small-strain shear modulus, and strain-dependent normalized shear modulus reduction and material dam...
