Tensile Strength of Granular Materials

Abstract

RECENTLY Carr1 and Douglas2 have commented on the equation for the tensile strength of granular materials as derived by V. Smalley and myself3, where σ is the tensile strength, Γ is a numerical constant, B is the bonding force of particle to particle, t is the thickness of the fracture zone (measured parallel to the stress direction) ,and D is the diameter of the spherical particles which make up the ideal granular material. As originally formulated3 the constant l′ had a value of 4.6. © 1967 Nature Publishing Group.
