Permanent Deformation Characteristics of Coarse Grained Subgrade Soils under Train-Induced Repeated Load

Advances in Materials Science and Engineering, 2017
This paper presents the results of a laboratory experiment that aimed to characterize the permanent deformation behavior of coarse grained soils. To evaluate the effects of the cyclic stress amplitude, initial mean stress, and initial stress ratio on the

Dynamic Parameters and Hysteresis Loop Characteristics of Frozen Silt Clay under Different Cyclic Stress Paths

Advances in Materials Science and Engineering, 2021
In cold regions, the long-term stability of engineering facilities is unavoidably influenced by the negative temperature, freeze-thaw process, dry-wet process, and dynamic loading conditions induced by earthquakes and traffic loads.

Characterization of the material response in the granular ratcheting [PDF]

, 2005
The existence of a very special ratcheting regime has recently been reported in a granular packing subjected to cyclic loading \cite{alonso04}. In this state, the system accumulates a small permanent deformation after each cycle.

Cyclic Degradation Characteristics of Undisturbed Soft Clay considering Anisotropy

Advances in Materials Science and Engineering, 2021
The stress-strain characteristics of soil depend primarily on the previous stress history and stress path, thus related to both the stress magnitude and direction.

Change of the yield stress in roll formed ERW pipes considering the Bauschinger effect [PDF]

, 2017
ERW pipes formed with the roll forming process show a yield stress distribution along the circumferential direction and their quality is strongly influenced by the magnitude and by the distributions of the yield stress.

New methodology for calculating damage variables evolution in Plastic Damage Model for RC structures [PDF]

, 2017
The behavior of reinforced concrete (RC) structures under severe demands, as strong ground motions, is highly complex; this is mainly due to joint operation of concrete and steel, with several coupled failure modes.
