Visualization methods are presented for the computed elastic response of underwater structures excited by continuous sound. Video animations show that the elastic behavior is dominated by waves whose displacement moves on paths around a center of oscillation. Such rotational waves, or turbules, occur even inside thin shells, the function of the waves being to change the direction of flexural motion. Computed results are presented for canonical shapes such as spheres and spherical shells. For more complex structures the elastic response will be similar. Different types of visualization of the amplitude and direction of vector quantities are discussed. Also discussed is visualization of the behavior of different elastic quantities in the structure.
