My understanding of Neuber's Correction/Method is that it allows for the estimation of nonlinear stresses from the corresponding linear elastic stresses by equating strain energy. I've recently been doing a little more research into the topic and would like some help understanding.
From reading...
I've been looking into the applicability of the Neuber Method/Correction for reducing elastic stress values in static analysis. I believe I have a pretty good grasp of the concept but have some question,
- Many of the online resources seem to apply this method when dealing with cyclic/fatigue...
I have been playing around with the idea of deriving stress concentration factors from finite element models and have some questions.
I have a simple model of a plate with a hole with an axial load applied. As I refine the mesh near the hole, the stress concentration factor I derive from my...
I just recently started doing buckling analysis on FEMAP and have a few basic question:
- From research I have done, it seems that if my shell elements have offsets, I have to use CQUADR elements for buckling analysis. Is this true? Why is this the case? Why are CQUAD4 elements not viable?

I was just introduced to fastener margin checks and have some basic questions on the topic.
From research, I've been doing fastener analysis through the following interaction equation:
MS = 1/(((Rt+Rb)^2 + Rs^2)^.5) - 1
where Rt = F_pullthru/Ptu
Rb = bending (somewhat involved process...
