Ulrich Lex Calculation RFEM RF-GLASS

How does the RF-GLASS determine bond stress?

Answer

In RF-GLAS, there are two different types of calculations. On the one hand, the so-called '2D' calculation. In this case, the glass structure is represented as a surface element. When considering the shear bond, an equivalent cross-section is determined using 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.

The RF-GLAS manual, Chapter 2, also provides further information on method of analysis.
