Abstract

In order to investigate volume change of sand due to cyclic loading, different tests were performed on hollow cylindrical specimens under drained cyclic simple shear condition. Correlation of accumulated plastic shear energy with volumetric strain and effects of different parameters such as initial confining pressure, initial anisotropic consolidation and strain amplitude on this correlation were studied. Test results showed that volumetric strain of sand under different initial confining pressures was almost same. Volume change of specimens with different initial anisotropic consolidations was also identical, except for initial stage of shearing. It was found that the correlation of volumetric strain and normalized energy was similar for different initial confining pressures and anisotropic consolidation. Test results showed that shear strain amplitude affected the volumetric strain-energy correlation. This effect was not significant when volume change was smaller. An average correlation of volumetric strain and energy can be used to predict volume change of sand under different strain amplitudes.

Prediction of Volumetric Strain for Sand under Cyclic Loading

San Diego, California

In order to investigate volume change of sand due to cyclic loading, different tests were performed on hollow cylindrical specimens under drained cyclic simple shear condition. Correlation of accumulated plastic shear energy with volumetric strain and effects of different parameters such as initial confining pressure, initial anisotropic consolidation and strain amplitude on this correlation were studied. Test results showed that volumetric strain of sand under different initial confining pressures was almost same. Volume change of specimens with different initial anisotropic consolidations was also identical, except for initial stage of shearing. It was found that the correlation of volumetric strain and normalized energy was similar for different initial confining pressures and anisotropic consolidation. Test results showed that shear strain amplitude affected the volumetric strain-energy correlation. This effect was not significant when volume change was smaller. An average correlation of volumetric strain and energy can be used to predict volume change of sand under different strain amplitudes.
