Hi,
can anybody suggest me about what can the negative eigenvalues in bucling analysis mean?
after having performed a buckling analysis, i got the eigenvalues like:
15.394
-15.397
15.925
-15.934
-16.213
16.223
the structure is geometrically symmetric, but i applied...
Hi,
i have a question about the eigenfrequency analysis. What is indeed the difference between the two eigenfrequency analyses;
1- structure is clamped,
2- structure is not clamped.
At first case, i get the first 6 modes equal to 0.0 (rigid body modes). But the 7. mode of analysis for...
Is it possible to extract the Participation Factors in all directions (X,Y,Z) and for all nodes in ABAQUS?
for instance, when the beam is diveded by 10 linear elements, and has consequently 11 nodes, is it possible to get the PF for each node in each direction?

Hi, everybody
is there anybody who knows how to get the MASS and STIFFNESS matrices from the ABAQUS and, maybe let them write down to a file?
Thanks in advance,
ridbay
