Patran 2013 Abaqus -- Nonlinear Analysis with Hyperelastic Material
Patran 2013 Abaqus -- Nonlinear Analysis with Hyperelastic Material
(OP)
Hi,
I'm a senior in mechanical engineering working on my senior design project and I've been trying to perform FEA on a part that utilizes rubber bushings, with Patran2013 Abaqus. I approximated engineering stress-strain from the bushing's load-displacement data to use for the hyperelastic material property inputs. The material properties for this model only consisted of hyperelastic material for the bushings and a linear elastic material for the piece that holds the bushings. I ran a nonlinear static analysis and noticed that something went wrong during the analysis. I checked the .msg file and at the bottom it said, "Translation Ended with Status = 0." However, I couldn't find any errors or warnings in the .msg file or any other file that was created for that run. What could cause this issue? (The .msg file is included at the bottom of this post)
Also, is it okay to use engineering stress-strain data to perform a experimental data fit using Patran2013 Nastran to obtain the hyperelastic material model coefficients to use in Abaqus?
Other Questions:
What Abaqus file displays all the errors like the Nastran F06 file?
Where can I find information about the different element formulations that Abaqus has to choose from?
Does Abaqus perform remeshing by default during nonlinear static analyses?
Any help will be greatly appreciated,
Thanks
