Abaqus FEA - Axisymmetric model of thin walled sphere (pressure vessel problem)

[@kar-dt1hk]

thank you sir for this video I have just one question concerning the riks method,
I have modelled a hollow hyperelastic sphere under internal pressure using axisymetric, using static riks,
My problem is that I don't know how to plot the pressure versus radial displacement curve.
please sir

Thanks a lot for sharing this video.

Great video thanks so much, would you have an idea on how to model the exact same sphere but with varying thickness. The thickness at the apex is 200mm and at the base is 500mm thick.

Well,..I think you could model it as the following 3 ways!?
1) Import Sketch File (such as *.igs) which has exact varying thickness dimension
2) Compute xy coordinates of varying thickness and just make a model using “create spline:through points” sketch option
3) Just make a model using “axisymmetric/deformable/wire” instead of "shell" and then create varying thickness using “shell thickness: nodal distribution” option in Edit Section

thank you for this video,hi sir, please can i help me, how can model a thick sphere under internal pressure with abaqus

[@Ahn.Eng.]

well..., you can just draw thick wall sphere geometry in your sketch step because we use the axisymmetric modeling in this vedio...that's all^^
