A Differential Stress-Strain; Relation for the Hexagonal Close-Packed Array of Elastic Spheres

摘要

A differential stress-strain relation is derived for a medium composed of a hexagonal close-packed array of elastic spheres in contact. The stress-strain relation is based on the theory of elastic bodies in contact, and includes the effects of both normal and tangential components of contact forces. Results of an experiment performed as a test of the differential stress-strain relation are presented.
