How to define a rigid plate?
I want to simulate the compression of a gyroid lattice, which I imported from nTopology as Abaqus input file. The assembly of the rigid plates along with the gyroid lattice is shown in the below figure:
To define the material of the plates as rigid I opted two methods:
- Defined the stiffness of the plates as rigid under the geometry tab in the mechanical model of the plates and imported the plates along with the lattice to another static structural module. But using this way I am getting the following error message:
2. Created a material with very high Elastic modulus (higher than the gyroid material by a factor of 10E10). But using this material the solution failed to converge. So I lowered the Elastic modulus to a value that is 10E2 times greater than the gyroid material, but it is giving me a higher stress value in the plates.
So, Someone please help me with how can I make the plates behave like a rigid body in this structural analysis.
Thanks a lot in advance for your reply!
