Development of an extended hyperbolic model for concrete-to-soil interfaces
… changes in shear and normal stresses and unloading-reloading. The hyperbolic formulation for interfaces (Clough and Duncan 1971) is accurate for modeling the interface response in the primary loading stage under constant normal stress. However, it has not been extended to model …

The Coefficient of Earth Pressure at Rest and Deformation and Densification of Granular Soils Subjected to Static and Dynamic Loading
… to 180 Hz), as well as 'cyclic loading' (loading-unloading-reloading, f ≈ 0 Hz), with various maximum dynamic stress amplitudes and durations of vibration, were applied to the sand specimens. A total of 155 oedometer tests with lateral stress measurement were completed. Particle modification, if …

A viscous-viscoelastic creep model
… are step changes in stress including complete unloading, reloading, step-up, step-down, and side steps in which one stress component was held constant while the other was increased or decreased. To predict the complex creep behavior under variable stresses of combined tension and torsion, …
