Complementary shear and transversal elongation modes in Generalized Beam Theory (GBT) for thin-walled circular cross-sections

摘要

This paper presents the theoretical fundaments of the complementary modes of Generalized Beam Theory (GBT) concerning the shear and transversal elongation energies of membrane's behaviour in hollow circular cross-sections. This study outgrows the classical assumptions of GBT, which impose no participation of shear and transversal elongation to membrane's strain energy.
