Hello everyone,
I am modeling a structure with shell elements in mechanical APDL. My problem is that the solution stops due to excessive element distortion in very low displacements thus giving unwanted results. Elements on the edges show this problem but not on the inside.
I cannot find a way...
Hello everyone,
I am running a nonlinear analysis with imperfections included by an eigenvalue buckling analysis with a factor of 0.1-0.5 ( the max dmx from buckling analysis is 1 , units are N/mm ) but the stiffness is much higher than the experimental results. How can I reduce the stiffness...
Hello everyone,
I am running a nonlinear analysis with displacement control. The analysis always stops at the same point producing the same graph of force displacement.
does this mean it reaches the limit of the structure?
Material nonlinearities and large displacements are enabled...
Hi,
What boundary conditions and loads ( how to apply the load) do I have to apply in order to validate my model and calculate the in-plane elastic properties?
The model is composed of a unit cell, meshed with Shell elements, with uniform thickness.
I want to compare them with the theoretical...
Hello there,
I am trying to find Wohlers curves or S-N curves for aluminum 5052. More specifically I want to calculate the fatigue life of a component made from this material with the Miners law but I cannot find fatigue information about the material.
Any help would be appreciated.
Thank you.
Hello everyone,
When I mesh my model this warning pops up about element shape. I tried to change the way of the mesh generation but it doesn't go away.
I want to run a non linear analysis and I think that this creates a problem for large deflection of the particular elements. How can I find a...
Hello,
Does anyone know how you can add imperfections to a model in APDL? More specifically I want to add imperfections in a non-linear analysis of a honeycomb unit cell.
Thanks!
