Mid-frequency endcap reflection and radiation coefficient extraction from FEM data
The response of a simple cylindrical shell terminated by rigid endcaps to various axisymmetric mechanical excitations is determined using the SARA 2-D finite element code. By assuming that the response of the shell is primarily composed of structural waves, which satisfy the fluid-loaded shell equat...

Zusammenfassung: | The response of a simple cylindrical shell terminated by rigid endcaps to various axisymmetric mechanical excitations is determined using the SARA 2-D finite element code. By assuming that the response of the shell is primarily composed of structural waves, which satisfy the fluid-loaded shell equations, the structural wave reflection matrix of the endcap is determined through an over-constrained system of equations.
