Ulrich Lex Calculation RFEM RF-GLASS

How does RF-GLASS determine the composite stiffness?


RF-GLASS distinguishes between two different types of calculation. On the one hand, the so-called "2D" calculation. The glass structure is represented as a surface element. When considering the shear bond, an equivalent cross-section is determined by means of the laminate theory. In contrast to this, there is the "3D" calculation. In this case, the layer structure is represented as a solid element in the calculation and thus the effectiveness of the stiffnesses between foil and glass is exactly determined when the shear bond is taken into account.

Further information about the calculation theory can be found in the RF-GLASS manual, Chapter 2.
