An effective combination of the method of boundary states and the Schwartz method for evaluating the stress-strain behavior of a cavity body

We estimated the efficiency of the Schwartz method combined with the energy-based method of boundary states (MBS) at each step of the iterative process and compared it with the direct application of MBS to a two-cavity elastic body analysis. We found better computational performance and a high level of convergence in the 3D case. The combined approach was used to estimate the limits of possible localization of a spherical cavity in a biconical body in a given surface load case.
