At 18:35, with the hose clamp for geometric nonlinearity, I think it is more like quasi-static, not purely static. By the way, I have a question, for the example of geometric nonlinearity, the hose clamp is still in linear region of the material after bending, isn't it? Thank you.
This may be a “quasi-static” analysis but the assumption we are making by choosing “static” is that the inertia and damping of the movement is going to be excluded. If this is not an accurate assumption, then a nonlinear dynamic study would be more appropriate. A “Nonlinear Static” study will allow for large displacements that occur over pseudo-time. We are unsure what material model was being used in this example. Typically this example is shown with an elastic material so the results will indicate past yield, but no permanent deformation will occur. Hope that helps! Thanks for watching!
Thank you for your answer. Just one more question, regarding boundary nonlinearity, could anything involving contact be regarded as boundary nonlinearity? In other words, boundary nonlinearity is contact nonlinearity, and vice versa?

I want to ask you about "tangent modulus" How can I choose this data correctly?
For steel it is more or less 1% of Young's module.
Can you describe more about how you modeled the boundary non-linearity condition

How do we analyze a cow? Assume a cylinder and add 10%.
can you mail me this ppt?
