Tensile strength of sand, palygorskite and calcium carbonate mixtures and interpretation with the effective stress theory

Influence of grazing on hydraulic and mechanical properties of semiarid steppe soils under different vegetation type in Inner Mongolia, China

“…Under wetter conditions the flattening and collapsing of the aggregates during the test decrease the inter-particle forces and result in less negative matric potential values. This is in agreement with the findings of Mosaddeghi et al (2006).…”

Estimation of surface shear strength in Zagros region of Iran — A comparison of artificial neural networks and multiple-linear regression models

“…In marls, because of enrichment with gypsiferous and limestone (mp1), CaCO 3 has larger value than in other geological units. Mosaddeghi et al (2006) showed calcium carbonate, is an important factor affecting the strength of the soil in arid regions. Slope of the area varied between 0 and 73 with 19.56% mean.…”

In-pore tensile stress by drying-induced capillary bridges inside porous materials

“…Another effect depends on the thermodynamic properties of a capillary liquid (and therefore its solvent properties) which differ from those of the free liquid [3][4][5][6][7][8][9][10]. On the mechanical side, capillary bridges pull on the solid(s) to which they are anchored, and so play a role in the compaction and the strength of soils (e.g., [11][12][13]), and in general of any granular wetted stacks (e.g., [14,15]). Furthermore, Scherer [16] and Smith et al [17] for gels, Tas et al [18,19] for massive solids (silicon chips), gave grounds that the capillary bridges are able to mechanically deform solid matrix, even at moderate capillary pressure.…”
