An Application of Visco-elastic Constitutive Equation by Generalized Voigt Model to Deformation of Clay

摘要

Clay has the time dependent characteristics of deformation such as the hysteresis loop of the stress strain curve, creep, stress relaxation, and secondary consolidation. In order to describe these behavior of clay, a viscoelastic constitutive equation by generalized Voigt model has been introduced.And the applicability of the model is discussed by comparision of the stress- strain- time behavior between the model and real clay.
