Which material model should be assigned to a timber contact solid?


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).
