Studies in soil dynamics have made unique contributions to the understanding of soil behavior for small, nearly elastic, strains, while studies in soil statics have shed light on the plastic behavior and strength of soils. This paper attempts to synthesize information from soil dynamics and statics into a comprehensive three- dimensional effective stress-strain relation for soils, that will apply to static and dynamic, single or cyclic loadings of cohesionless or cohesive soils, accounting for inherent and stress induced anisotropy. A set of equations is presented that provide the general framework. Many of the details have been worked out, but others require further investigation. Some of the interrelationships between stress-dilatancy, critical state soil mechanics, work-hardening plasticilty, empirical equations for modulus and the hyperbolic stress-strain relation are demonstrated. Although an effective stress-strain relation is formulated, it is believed that it will ultimately be applied to undrained and partially drained soils. It is believed that the ulitimate solution to these problems lies in effective stress analysis. Of course, this does not diminish the importance of undrained strength analyses to current practice. /Author/
