Abstract:

The physical significance of the terms in the Doubly Asymptotic Approximation DAA are evaluated. Additionally, the computational aspects of the terms are discussed. Two simplified versions of the DAA are proposed. These versions are referred to as the Plane Wave-Added Mass PWAM cylinder approximation and the PWAM plate approximation. Both approaches are evaluated via comparison to exact solutions and full DAA solutions. The PWAM plate approximation is shown to give results almost identical to the full DAA for problems dominated by structural deformation. Both methods appear to do a good job of picking up shell translation response. Author
