Abstract:

This report examines direct time integration techniques for the transient response analysis of fluid-structure interaction problems treated with the Doubly Asymptotic Approximation. Efficient solution of the equations of motion is achieved by a modular computer implementation in which separate fluid and structure analyzers are interfaced through extrapolation of the coupling terms. Because conventional realization of this technique is handicapped by severe time-increment limitations, a versatile formulation is developed that circumvents such limitations, achieving unconditional stability.
