An integral bound on the strain energy for the traction problem in non-linear elasticity with sufficiently small strains

Research output: Contribution to journalArticlepeer-review

Abstract

For the fraction boundary value problem in non-linear elastostatics for a body which is convex in its undeformed reference state and with the assumption of sufficiently small strains (but not necessarily small displacement gradients), an upper bound is obtained for the elastic strain energy in terms of the L2-integral norms of the surface tractions and body forces with the constant depending only upon the ratio of the outer and inner diameters and the physical constants of the material. This result extends previous known results in linear elasticity (infinitesimal displacement gradients) and finite elasticity (small but finite displacement gradients) into the small strain theory of non-linear elasticity.
