Abstract

The mechanical response of shelly carbonate sand differs significantly from that of more common silica sand and is yet poorly understood. A series of one-dimensional compression tests was performed on this material inside an x-ray scanner and high resolution computed tomography (µCT) images were used to investigate the evolution of the internal microstructure. In addition, numerical simulations were carried out using a newly developed micro Finite Element (µFE) [1]. The capability of the numerical model to measure the stress within a grain with complex morphology is demonstrated here.
