The effects of multi-scale particle shape characteristics on the small-strain stiffness of
granular soils remain controversial. This study revisits this topic using well-calibrated three …

This paper presents a numerical investigation about the effect of particle shape on small

Shear properties of the rock-concrete interface are critical to the stability of deep
underground engineering projects, particularly in high-temperature environments caused by …

Realistic constitutive ground models are critical in the evaluation of soil‐structure interaction
problems and the assessment of key design parameters in the seismic analysis of …

Despite the significant progresses in discrete-based numerical studies of granular materials,
most efforts have been placed in the study of large deformation problems and there are …

In the study we experimentally examine the influence of elastic properties and surface
morphology on the inter-particle friction of natural soil grains. The experiments are …

This paper presents a numerical method to investigate the critical-state behaviors of the soft-
