Hello, I would like to simulate the deformations of a wooden board (for stair treads) and for this I would like to know if SolidWorks Simulation allows to deal with an anisotropic material? And if so, can we adjust the different directions of the woody plane?
Impossible to find a result by searching on google, so I'm trying my luck here:)
Have a nice day
Hello @matthieu.lostenlan
The answer is no for the good reason is simple reason that wood does not have stable characteristics because from one board (plank, etc.) to another even taken from the same tree the elasticity in all directions will not be the same, therefore we cannot use Von Mises, nor Tresca
Apart from an orthotropic simulation to have an approximate value I don't see a solution (but I don't know everything, far from it)
It is certain that you will have to define your materials in SW for at least the Young's moduli and Poisson coefficients (here tables ) on the other hand I have not found reliable tables for the coefficients of thermal expansion, nor for limits the elastic limits of these materials.
You can look here on page 59 for a good approach to the problem but with a sawmill batch analysis. This would mean that you would need to know the module for each batch and create or modify the criterion in SW for each simulation. There are several theses that deal with or make an approach to the problem.
However, I suggest you look at the following link although the examples they give seem ambiguous to me. You can always get in touch with them to see if it fits your needs.
Let's also wait for the opinion of our colleagues who are specialists in simulation; of which @m.blt
Kind regards
Thank you for your answer;
Indeed, I had not taken into account that the wood would change property according to many criteria (its aging, etc....) as well as the processes of obtaining these famous boards.
The links you have given will allow me to start again with a new design approach, which I hope will be more fruitful:)
Have a nice day
