1.13.16 Response of beam elements to a planar wave

Products: ABAQUS/Standard  ABAQUS/Explicit  

Simulating the response of submerged structures of simple geometric shapes to various underwater explosions constitutes an important part of the validation of any fluid-structure interaction code. In this example the ability of ABAQUS/Standard and ABAQUS/Explicit to model the response of beam elements to a planar linearly increasing wave is illustrated. The results obtained using ABAQUS are compared with those determined theoretically using the equations of Hicks.
