Invalid Material for Timber Surfaces

Why do I get an error message about invalid material when defining timber surfaces?


Answer:

For an isotropic material model, the Poisson's ratio is fixedly coupled with the modulus of elasticity and the shear modulus. If the Poisson's ratio becomes too large and exceeds the limits, isotropic material behavior is no longer present. To avoid the problem, we recommend creating an orthotropic material for surfaces and solids. For members, it is still necessary to select the isotropic material model. In this case, you can ignore the message.
