Document Summary
A sandwich panel is configured such that one forms the faces and the other the core to give a structure of high bending stiffness and strength at low weight. Sandwiches are used where weight saving is critical: in aircraft, trains, motor vehicles, portable structures, and sports equipment. Light core, stiff faces they must also tolerate the environment in which it operates. The faces, each of thickness , carry most of the load, so they must be stiff and strong. The core, of thickness , occupies most of the volume. We can easily calculate the stiffness of a sandwich panel with given materials and dimensions however this does not make it easy to compare to different solid material pane. To address this, we can also think of the sandwich panel as a material with its own set of properties, calculating equivalent material properties for the hybrid.
