Here is my problem statement and input file:
I am modeling an indentation of an incompressible, hyperelastic material. The following are the specifications used:
Membrane diameter = 5 um
Indentor diameter = 0.5 um
Membrane thickness = 0.005 um
C10 = 2.7e-9 N/(um^2)
The material is to be...
Parts all check out. This is such a puzzle!
My thought is that the discrepancy is related to either the interaction or mesh; however, I've checked each setting one-by-one and can't seem to resolve the issue. Are there specific settings that can alter the accuracy of the model?
Thank you Rob; very informative! However, your suggestion does not entirely apply to my current situation. I am trying to re-create an Abaqus model from literature as well as a CGMD model created in my lab--both of which yield the same results. With my simulation, however, my forces are...
Thank you for your suggestions; I tried them with little success. I've also tried changing parameters one-by-one to see where the issue may be coming from, but I just can't resolve things. My reaction forces are still an order of magnitude or so lower than the desired results.
I have...
Hello,
I am trying to model the deflection of a rubber "membrane". The "membrane" is 250 mm in diameter and 0.5 mm in thickness; it is meshed with C3D6H elements and is modeled as an incompressible, neo-Hookean material with C10 = 0.17 MPa. The material is deformed 127 mm via...
Thank you again! Could you please give a little more guidance as to the interaction I should further investigate / assign? I have been trying to test / use different interactions applied to the inner walls, but have yet to see positive results.
I am attempting to model an ellipsoid shell with hyperelastic material properties--one side of the ellipsoid is tied to a rigid sphere that is held stationary while the other side is tied to a rigid sphere that is pulled with a specific concentrated force. However, during deformation, the top...
