摘要

This chapter addresses nonlinearly coupled stochastic FSI in moving domains where domain motion is significant-unlike Chap. 8 ’s fixed-interface model. The system couples a 2D viscous incompressible fluid with a linearly elastic shell across a stochastically moving interface, driven by multiplicative noise affecting both fluid (volumetric) and structure (boundary).
