Dear friends,
Imagine that there is a component/structure that is subjected to one harmonic load with frequency Wloading and that I would like to make an assessment of fatigue life of it. Let's consider the load as F(t)= Lmax*sin(Wloading*t).
And imagine that the 1st natural frequency of this...
In the Finite Element Method, an element's Jacobian Matrix relates the quantities wrote in the natural coordinate space and the real space. The bigger the element is distorted in comparison with a ideal shape element, the worse will be the transformation of the quantities from the natural space...
Hi,
Frequently I have to do fatigue life assessment of parts using the results of an FEA. Well, the matter is that I've been studying fatigue analysis for a while, specially the S-N approach, and there is an issue that is botthering me: It's about the modifying size factor "Csize".
I've took 7...
Hi all,
There is a cast-iron part, with dimensions 300x300x500mm, that has to be lathed. The part is fixed at just one side, at a big lathe headstock. The problem is that it`s not possible to mantain one diameter inside tolerances, probably beacause this part is not axisimmetric (large...
