A PANEL WITH TWO-DIMENSIONAL CURVATURE

摘要

A panel (2) having a panel topology and a mode-shaped panel are provided each having pre-defined bending strength characteristics, vibration characteristics and acoustic characteristics improved from those of a flat panel. A panel (2) having both panel topology and a mode shape is provided having further improvements. A panel (2) having a multi-layered structure is provided having at least one layer that has either a mode shape or a panel topology, and other layers that may be flat or curved and that may be damping layers.
