Definitions
- the filling material is compressed when the sheet is subjected to a bending load, so that the bending stiffness of the sheet quickly decreases even under relatively light loads.
- the aluminum sheet prevents the cover sheets from coming close together because the aluminum sheet supports the cover sheets. With increasing bending load, however, there is a risk that the cover plate opposite the point of application of the bending force acting as a tension belt tightens and over the aluminum plate the cover plate acting as a compression belt and facing the point of application of the bending force buckles against the direction of force of the bending force.
- the proportion of the filling material with the soft stress / strain characteristic determines the bending line of the double-layer sheet. If the bending force increases, the proportion of the filler material with the harder stress / strain characteristic becomes effective, which prevents the cover plates from coming closer together, thereby reducing the moment of inertia of the double-layer plate.
- the behavior of the filling material when compressing the double-layer sheet which is characterized by the two stress / strain characteristics without the support effect of the knobs, can be determined, for example - 4 -
