PROBLEMS OF SMALL STRAINS SUPERPOSED ON FINITE DEFORMATION IN VISCOELASTIC SOLIDS

摘要

In this report, certain problems of stress relaxation, due to small strains applied to a deformed viscoelastic material are examined. The initial strain is assumed nonlinear, and the material completely relaxed. The solutions obtained are useful in the design of experimental techniques for measurements of visco-elastic properties under finite deformation.
