Question
Which material model should be assigned to a timber contact solid?Answer
In the case of timber, the "Orthotropic Elastic/Plastic 3D" material model has to be assigned to the "Material" solid type (Figure 01).
Since the program considers the "Contact" solid type as a member, it usually requires the isotropic material model (Figure 02).

Modeling Downstand Beams in Cross-Laminated Timber Constructions with Ribs
This time, we want to look at modeling downstand beams by means of ribs.
The cross-section resistance design analyzes tension and compression along the grain, bending, bending and tension/compression as well as the strength in shear due to shear force.
The design of structural components at risk of buckling or lateral-torsional buckling is performed according to the Equivalent Member Method and considers the systematic axial compression, bending with and without compressive force as well as bending and tension. Deflection of inner spans and cantilevers is compared to the maximal allowable deflection.
Separate design cases allow for a flexible and stability analysis of members, sets of members, and loads.
Design-relevant parameters such as the stability analysis type, member slendernesses, and limit deflections can be freely adjusted.
