An accurate finite deformation elastoplastic theory based on the logarithmicstrain is transplanted from infinitesimal deformation elastoplastic theory.
引入对数应变，将小变形弹塑性理论移植到有限变形理论之中，形成了一套精确的有限变形弹塑性理论。

This logarithmic decay ratio of the shaft set is in direct proportion to the ratio of the energy dissipated per cycle to the peak strain energy.
