  • 3.1 Moment of Inertia “I” (mm4 )

Property of a section that quantifies its amount of mass (area) with respect to its center of gravity. It directly influences the tension and deflection obtained in a panel under a given load (the higher the inertia, the lower the tension and deflection for the same load).

  • 3.2 Modulus of elasticity “E” (N/mm2 )

Also known as Young’s Modulus, it is a constant characteristic of elastic materials that relates the force applied to the deformation or displacement obtained. The higher the modulus of elasticity, the smaller the deflection for a given load.

  • 3.3 Stiffness “EI” (kNcm2 )

It is the product of inertia and elastic modulus. For a given load and support configuration, this is the only data required to obtain the deflection on the panel. The greater the stiffness, the lesser the deflection.

  • 3.4 Elastic limit “R p0,2” (N/mm2 )

Limit stress supported by an elastic material up to which the deformation obtained is 99.8% recoverable after removal of the applied force. The higher this limit, the more difficult it is for the acting loads to cause permanent deformations in the panel.

  • 3.5 Ultimate ultimate breaking load “Rm” (N/mm2 )

Stress at which a material breaks. Once the yield stress has been exceeded, the material continues to deform without breaking, but in a plastic form (non-recoverable deformation). When the ultimate limit stress is reached, the material breaks.

  • 3.6 Elongation at break “A”(%)

Increase in length (in percent) of an element from the time the yield strength is exceeded until failure occurs.
