Abstract

Strain localisation behaviour in a partially saturated dense sand specimen during triaxial compression has been observed by microfocus X-ray CT and image analyses of CT images. Digital image correlation (DIC) has provided displacement and strain field in the specimen in a macroscopic point of view. In the meantime, trinarization by a region growing segmentation technique has given local void ratio and degree of saturation microscopically. Through these image analyses of CT images, the progressive strain localisation behaviour and microstructural changes in the shear band have been quantitatively studied.
