Substructuring Method for Responses and Response Sensitivities of Nonlinear Systems
Since the nonlinearity is common in practical structures while linearity is an idealized assumption, the substructuring method is extended to the nonlinear systems in the following chapters. In this chapter, Kron’s substructuring method presented in Chap. 2 is extended to compute the structural responses and response sensitivities of nonlinear systems (Tian et al. 2021). The global structure is partitioned into the linear and nonlinear substructures. The linear substructures are reduced to the modal coordinates spanned by a few master modal responses, and the nonlinear substructures are localized. The structural responses and response sensitivities are computed efficiently from the reduced vibration equation.
