The use of lightweight sandwich elements in engineering structures requires a basic database of mechanical and physical specifications of their components to determine their structural design criteria.
This research paper aims to highlight the effect of core density of locally produced sandwich panels with a polyurethane core on their elastic modulus and the level of compressive stresses that can be applied to the panel surface without compromising the functional performance of these elements due to local deformations that accompany the application of these stresses.
This research has made it possible to explain this effect of core density in a simplified form that is helpful when carrying out practical applications on these lightweight sandwich elements.
