Hi everyone,
Why am I obtaining differents eigenvalues for the same model, using either Lanczos or Subspace method?
When I use the lanczos all the eigenvalues are positive, but with Subspace all of them are negative. They are not similar at all.
Please help me to understand this.
Thanks in...
Hi,
I performed a buckling analysis for a composite panel obtaining several closely spaced eigenvalues. Then i did a static riks analysis for study the non linear behavour of the structure. Theorically the load proportionally factor has to be the same as the correspondant eigenvalue, is it...
Hi guys,
I am new in the forum, and in FEA work! I am carrying out a buckling analysis with abaqus. When I open the .odb file I can see the buckling modes and their respective eigenvalues. I can not understand the meaning of the displacements legend. When the displacement is less than one, is...
