Relation between Microstructures and Macroscopic Mechanical Properties of Earthen-Site Soils

Abstract: While the macroscopic mechanical properties of earthen-site soils have undergone extensive experimental and modeling studies, few research efforts focus on the relationship between the overall mechanical behavior and micro-pore structure. We developed a microstructure-based finite element model to investigate the influence of micro-pore structure on the macroscopic mechanical behavior of earthen-site soils. Scanning electron microscopy images of the untreated and consolidated soils were processed to compare th… Show more

“…Dry coral sand is considered as a two-phase system composed of solids and gases. The threshold segmentation method was employed to divide the processed image into two regions, namely, coral sand particles and voids (Matsushima et al, 2009;Zhao et al, 2015;Zhang et al, 2022b). The binary image of coral sand was thus obtained, and microstructural parameters of voids were then extracted.…”

“…Under these assumptions, as often adopted in the literature as a first approximation for porous materials (refer e.g. to [56,57]), the RVE of the microscale can be defined through a face-centred cubic cell as shown in Fig. 5 (a).…”
