Good day,
Whenever we define large displacement and large rotation, for general engineering people, how do we define how large is a displacement and rotation must be to consider them large?
Thank you in advance.

Does anyone use LS-Prepost 4.3 on Mac? When I want to open d3plot files LS-Prepost quits unexpectedly on mac.
I have implemented the rate-independent strain gradient plasticity framework of Niordson and Hutchinson (2003) in UEL. I was able to validate the results of the shear of infinitely wide thin layer between two rigid surfaces (Niordson and Hutchinson, 2003). However, the UEL subroutine fails to converge for the more complex problem of the shear of finite width slab. I suspect the convergence issues are arising out of internal elastic-plastic boundary conditions and the yield criteria. I have few doubts in this regard.
Dear friends,
I was curious about the time varying loads on the helicopter blades in the forward flight. After reaching lots of books and documents, I came to know that some control (cyclic) is applied to take care of the dissymetry of lift in the forward flight. My question is, if the dissymetry of lift is eliminated by applying the cyclic control or by blade flapping (whatever), then why the load should vary with time for the 90 and 270 position of the blade? Can anybody explain this? Please let me know the justification. I am really curious about it.
Thanks
I'm modeling a column under Constant Axial load (Y-axis) and Cyclic bidirectional loading (X & Z-axes). Does anyone have experience how to apply Cyclic bidirectional loading in ABAQUS? See the attached picture.
Hello Everybody,
one interesting question:
As I found, there is no possibility to use XFEM in Abaqus Explicit. !!!
maybe, somebody has any idea or trick to use XFEM in Abaqus Explicit?!!!
thanks in advance,
I have a question which I don not understand. In the simulations of deforming of an anisotropic material like aluminum alloy sheet, different coordinates applied to the specimen model may leads to different results. But why? I mean for example, when the uniaxial tension specimen model is in rolling direction or in transverse direction, the anisotropic yield criterion is the same, the associated flow rule but why the results are different?
