Long-term cyclic loading applied to clay at stress levels lower than the critical leads soil deformation without inducing damage. The Monismith model is well-known for its simplicity and ability describe trend of cumulative plastic strain under loading. However, simulated increases indefinitely with number cycles until damage occurs. At levels, tends be stabilized an increasing cycles, ultimately limits applicability model. To address this issue, a series axial-torsional bi-directional tests...
A series of undrained cyclic torsional shear tests was conducted to investigate the effect loading frequency on liquefaction characteristics saturated sand using a hollow cylinder apparatus. The test results show that dilative and contractive tendencies various sands are not only related physical properties sand, but also affected by frequency. Under low-frequency loading, has behaviour, excess pore water pressure fluctuates after initial soil maintains ability resist some extent...
Small-strain shear modulus (G0) is a fundamental property required in dynamic analyses. For sandy soils, G0 may be affected strongly by particle characteristics such as uniformity coefficient (Cu), mean size (d50), fines content (FC), and shape. Based on an extensive experimental study of the mechanical behavior coral sands, this paper proposes new formula for predicting soils with various Cu, d50, FC, shapes. A notable feature use extreme void ratios (maximum ratio emax minimum emin)...
Granular materials, such as rockfill materials and carbonate sand, exhibit complex mechanical behavior, which is affected by particle breakage under elevated pressures. In this study, we present a relative model based on mean stress, void ratio, strain. We further consider the effect of critical state line. A hypoplastic constitutive developed incorporating state. The validity shown comparing numerical experimental results drained triaxial tests.
