TENSILE STRENGTH, SHEAR STRENGTH, AND

It is generally accepted in geotechnical engineering that non-cohesive materials such as sands exhibit no or negligible tensile strength. However, there is significant evidence that interparticle forces arising from capillary and other pore-scale force mechanisms increase both the shear and tensile strength of soils.
