The current paper is focused on analysis of delamination of a semiring engineering structure attached to non-linear elastic torsional springs that are situated in the semiring plane. The semiring has arbitrary number of circumferential layers made of nonlinear viscoelastic materials that are inhomogeneous along the thickness. The semiring undergoes time-dependent bending rotation at a given cross-section. The delamination is treated from view point of the strain energy release rate (SERR). A methodology for determination of the SERR in semirings attached to torsional springs is worked out on the basis of analysis of the energy balance. The results yielded by this methodology are verified by extracting the SERR from the complementary strain energy. The study presented in the paper provides useful insights into delamination performance of semiring engineering structures which is a premise for enhancing the structural reliability. The effects of various parameters of the semiring geometry, inhomogeneity of layers, non-linear constitutive laws of torsional springs, external loading, number of springs and their locations are examined and clarified.
