Calculation of Three-Layer Panels with Polyurethane Foam Filler Taking into Account the Rheological Properties of the Middle Layer

The article deals with the processing of shear creep curves for foamed polymers, as well as a technique for calculating three-layer beams, taking into account the nonlinear creep of the aggregate. The Maxwell-Gurevich equation is used as the creep law. An example of calculation of a three-layer pane...

Zusammenfassung:The article deals with the processing of shear creep curves for foamed polymers, as well as a technique for calculating three-layer beams, taking into account the nonlinear creep of the aggregate. The Maxwell-Gurevich equation is used as the creep law. An example of calculation of a three-layer panel with a middle layer of polyurethane foam is given.
