Abstract : As part of the overall U. S. Navy program to reduce the acoustic energy radiated into water by naval ships, the use of laminated materials for use as foundation structures was investigated. This material is composed of alternate steel and viscoelastic layers, and is contemplated for its simultaneous use as a load carrying member and a dissipator of time-varying energy passing through it or impinging upon it from the surrounding air.
