Accumulative Plastic Strain of Frozen Silt Clay under Cyclic Loading

Applied Mechanics and Materials, 2014
To evaluate the influence factors of accumulative plastic strain of frozen silt clay, the dynamic cyclic triaxial tests with stress-controlled are conducted to investigate the behaviors of frozen soil induced by cyclic loading. The relationships between accumulative plastic strain and vibration numbers for frozen silt at different dynamic stress ...

Accumulative plastic strain of thawed saturated clay under long-term cyclic loading

Engineering Geology, 2017
Abstract Accumulative strain of subgrade soil is crucial for designing the subgrade structures and maintaining the long-term performance of pavements. Due to the effects of freeze-thaw cycles in seasonally frozen region, subgrades filled with clayey soil usually are exposed to an increasing risk of turning into a saturated condition.

Low-Cycle Fatigue Crack Propagation Behavior of Cracked Steel Plates Considering Accumulative Plastic Strain

International Journal of Steel Structures, 2019
AH-32 steel has been widely used in ship and marine structures but not been extensively studied for low-cycle fatigue (LCF) crack growth characteristics. The objective here is to explore the evolution mechanism behind LCF crack propagation behavior under different load conditions, for which the investigation of experimental and numerical simulation is ...

Cyclic mobility following plastic strain accumulation in sand

Géotechnique Letters, 2023
Hybrid failure modes/mechanisms under non-symmetrical cyclic loading (partial stress reversal) have received little attention. This paper presents data from cyclic undrained triaxial tests of sand, with initial static shear stress, to investigate a hybrid failure mechanism that controls the behaviour of dilative sand in a narrow range of non-symmetric

Direct Analysis of Elastic-Plastic Strain Ranges and Accumulated Strains Considering Stress Stiffening

Volume 1: Codes and Standards, 2022
Abstract Many pressure vessel and piping components have to withstand high internal pressures and are therefore thick-walled so that geometric effects such as stress stiffening need not be accounted for. However, thin-walled, or moderately thick structures may be sensitive to these effects.
