Hello!. I guess that could be ANSYS programme

That may not be a matter of the simulation tool, but of the applied material model within it. In one week I'll be back at office. If you like come by and we can discuss this issue further.

I agree with Axel. The software should not be important. However, some software's are more user friend, therefore, many researchers are using them. On the other hand some other are using software's having FEM capabilities. Depending upon your needs.

This is a very good question. I agree with Axel, too. For simulation of wood, I think that the reliability is low, even for simulations at elastic stage. Since the general theoretical framework is the same for the current commercial FE softwares, e.g. ABAQUS, ANSYS and LS-DYNA, however, all are not helpful for really simulations of wood. Although LS-DYNA have some built-in material models, however, however, are for composite materials. Wood properties are more complicated than composite materials, even at the elastic stage. Let alone in the plastic stage, damage stage. All the challenges come from the lack of a proper wood model.

1) We should conduct deep researches on the elastic constitutive model for wood.

This means that a better knowledge of wood anistropic properties is needed. Usually, we make orthotropic assumption for wood, having 12 elastic constants. However, the tesing methods need improvements, especially for shearing.

Another, the constants are highly physically and growth characteristic dependent, i.e. a quantitative relation should be given between 12 constants and the density, MC and growth ring width.

2) we should conduct researches on the wood properties under conplexstress state, e.g., bi-axial, normal-shearing and tri-axial stress state.

... ....

3) Based on 2), a better yielding/strength/ failure criterion is needed.

... ....

4) Based on 2) and 3), a better constitutive model for wood is needed.

... ....

5) If possible, some special FE subroutines and softwares should be coded for wood and timber members and finally timber structures.

... ....

Therefore, there are many topics on wood material model and deserve deep researches in future.

OPENSEES is a good software for simulation of seismic performance of wood structures.

I recommend you to read the works of Carmen Sandhaas. He really does well in the simulation of timber structure by using ABAQUS with UMAT subroutines.

You can also try Comsol Multiphysics from my point of view.

Thanks dear Yue

Opensees is a good software to simulate CLT panel. The methods can be found in my papers:

However, my suggestion is to think about the model and the numerical approach rather than the software. The numerical approaches can be easily implemented by coding and the software is only a tool to speed up this process.
