- Abstract
- A numerical procedure for computing the nonlinear transient response of coupled fluid-structure systems is developed. The study concentrates on two types of nonlinear behavior in concrete dams: water cavitation and tensile cracking of concrete. The fluid is considered compressible and inviscid, undergoing small amplitude motion. The computational procedure employs a mixed pressure-displacement finite element formulation for the fluid and a displacement formulation for the structure. Results demonstrate that concrete tensile cracking has an important effect on the displacement and stress responses of gravity dams, while water cavitation has little influence.
