Stress effect decay estimates for anisotropic material in a semi-infinite strip. (English) Zbl 0946.74022
Summary: We derive the Saint-Venant’s principle for anisotropic material in an end-loaded semi-infinite elastic strip. Energy method is used to establish the lower bound for the decay of stress. We give also an explicit estimate in terms of elastic constants of the anisotropic material. Finally, a numerical example for an end-loaded off-axis graphite-epoxy string illustrates the results.
