Hi,
I am going to conduct a simulation using Glulam beams GL24C and GL30C. I am trying to set these up as a new material. There is no Poisson's ratio given and I am wondering which Model Type is best.
Regards,
Oliver

Poissons ratio is definately necessary for FEA. Stress is calculated with the strain, E, and poissons ratio (Hooke's law - Wikipedia, the free encyclopedia )

Hi Oliver,
For isotropic materials you can find the poissons ratio with the Youngs and Shear modulus (see attachment). In this case the beams are made of orthotropic material, so using the table from the attachment maybe more complex.

Hi.I'm not a professional but this might help you. As far as I remember the Poisson's ratio is not necessary for FEA simulation. But if you realy need that ratio and can't find anywhere, your last option is to measure it. I know it sounds hard to do but that's the only way if you're working on a project which you are being paid to do.
