Hi all,
I am struggling with the concept of applying different PSD curves in multiple directions (x, y and z) to the supports of a structure. Assuming that there is no correlation between the different PSD curves, how is determined the response of the structure in one particular direction?

Hi all,
I'm currently building a relatively large structural model in ANSYS Workbench and I need your help in an intriguing issue that has come up.
Since this is a relatively complex geometry, I need to divide it into simpler "blocks" in order to have a nice structured mesh. To do so I am...
Hello all,
Sorry for the long post but it is worth it.
I am currently analyzing the response of a beam shaped solid (clamped at one end) to a base (displacement) random excitation. I am interested in knowing the 1-sigma displacements (RMS values) of some nodes in the same direction of the...
Hi all,
I'm currently trying to run a nonlinear static analysis of an engine mount using this simplified 3D geometry:

The material model is assumed to be a linear elastic one with a...
Hi all,
I'm currently having some troubles analising a thin walled conical conduct subjected to the atmospheric pressure on the outside (vacuum inside). The problem is that no matter what I do I can't find the buckling load (or mode) with a non-linear analysis: the structure simply deforms like...
