Hi all,
In Abaqus membrane element, there are two Poisson ratios can be set. One is the Poisson ratio of the material of the membrane and the other one is called "effective section poisson ratio", which can be set to 0 in order to fix the thickness of the membrane. Does anyone know what is...
Hi John,
Thanks for the reply! The distortion still occurs if I change the pressure load to like 1000, which is half of Young's modulus. Thanks for reminding me that such a deformation is unrealistic which I overlooked. I am new to this kind of stuff.
Hope to get more help from you!

Hi Rob and OptiEng,
Thanks for replying. Suppose in this simulation, only standard units are used. The size is 200m, and E is 2000pa and the pressure is 3000 pa. I did not use MPa for E. My sole purpose is to test ALE. Even though Abaqus completed the analysis, I still see distortion in the...
Hi Abaqus gurus,
I am working on a simple 2D simulation with two circles. The inner circle is inflated with a constant pressure (3000pa). The material is a simple linear elastic model (E=2000, poisson=0.45). Even I have used ALE adaptive meshing to control mesh distortion, the final result I...
Hi Rob, thanks for replying! The model is used for human tissue,with uncertainty in mechanical properties (due to the non-invasiveness). I just start with simple elastic materials.
I have already made the remeshing frequency of ALE to 1 with 10 sweeps. Do you think what may be wrong? It...
Hi all,
My Abaqus/explicit ALE simulation terminates before the target pressure load can be achieved. The geometry is consisting of 4 concentric circles, and one other circle which will be inflated with a pressure (DSLOAD). Due to this expansion, ALE is used to control mesh distortion. I...
