Mechanical Strength in Sandwich Panels

   The choice of sandwich panels in buildings is made by considering the load-carrying capacity. Factors such as dead weight, wind load, snow load, and temperature affect the structures alone or in combination.

   Since sandwich panels are composite materials filled with polyurethane or rock wool between 2 metals, their behaviour against the loads they are exposed to should be carefully evaluated.

   Metal surfaces with low modulus of elasticity and filling materials have difficulty even carrying their own weight independently. In the composite case, a new system is formed with a better load-carrying capacity than each layer, thanks to its high shear and bending strength.

   The trapezoidal form of the sandwich panels and the strength of its inner filling material are also very important in their carrying capacity.
