Is the Von Mises Stress RMS output from Random vibration analysis the actual stress?

The stresses from modal analysis are not the actual stresses. They doesn't have meaning but can be used to compared some areas of the modal to other areas so that we know which area has higher or...

Does Modal Analysis take into account contact with other parts?

I use LS-Dyna as the solver for my analysis. My model has two parts connecting with some spotwelds. I defined a contact for them, but it doesn't seem to work.

Can someone explain to me the linearity of the modal analysis?

I know that modal analysis decouple ODEs so that the modal ODEs can solved individually. The modal superposition method is used to get the total response of the system. Since modal solutions can...

Can random vibration analysis be performed as an explicit instead of implicit analysis?

I know that commonly random vibration analysis is performed as implicit analysis and uses modal superposition method, but can it be performed as explicit analysis? How can we do that? and what are...

What is a random vibration analysis? And Why do we need to run modal analysis first before performing random vibration analysis?

I'm new to random vibration analysis. Recently I started to try it out in LS-Dyna. I had a small success run with a single part from a tutorial, and my end goal is to able to successful perform...
