Change in the elastic properties of partially saturated limestone during drying conditions

نویسندگان

چکیده

The article presents the results of an experimental study water content effect on elastic properties a limestone specimen (Young’s modulus and Poisson’s ratio) during drying after its partial saturation. We first constructed diagrams saturation loss, then their basis we selected mode specimen. was subjected to uniaxial compression in range small reversible deformations. chose loading exclude formation accumulation microstructural changes (damages) material. tests were carried out at certain intervals natural values ratio calculated based stress-strain accordance with standard STO 05282612-001-2013 adopted Chersky Mining Institute North SB RAS. analysis test revealed features mechanical behavior specimen, which indicate disproportionate even non-monotonic dependence content. propose hypothesis that allows us explain detected effects qualitatively.

Finite element modelling of the effective elastic properties of partially saturated rocks

Simulation of effective physical properties from microtomographic 3D images of porous structures allows one to relate properties of rocks directly to their microstructure. A static FEM code has been previously used to estimate effective elastic properties of fully saturated monomineralic (quartz) rock under wet and dry conditions. We use the code to calculate elastic properties under partially ...
