Hmm I see, thanks for clearing out the issue with how to assign a "known" area to the spring.
Also I will def. have a look into connector elements, just had a quick view and it looks good!.
Well since I've fibbeled around alot with the cae-inputfile- i woulnd't want to post that, it...
Thanks Martin!
That is a good idea. Anyhow it is not exactly what I need, so i'll redefine the problem.
I'm simulating a plate with an impact damage that is subsequently exposed to a compressive load. So using symmetry, the damage is a quarter circle in one of the corners of the wide plate...
I had a post quite recently concerning to find strain energy release in dent growth induced by buckling, I have problems running that/finding a way to get the rates so I am trying another approach with spring elements, SPRING1.
They actually comply alot better with existing theory. Anyway,
In...
cause, my supervisior has made a closed form criterion for dentgrowth in sandwichpanels and I want to numerically confirm the accuracy for a circular damage on o sandwichpanel. And the energy realese rate (Gc) is a very convenient way to describe the growth rate due to it's clos relation to just...
Hi
Well the thing is that there is'n really a crack, so the vcct elements are not what I need,, see . since the core elements get crushed by the advancing facesheet buckle ´. But maybe the second alt. with duplicate nodes between the face and core sections would do it?
..To clearify : I don't...
Hi !
I'm modelling a sandwich structure using one part which I have partioned into a core block and a face sheet. The core is elastic-perfect plastic and the face sheet with engineering constants. Initially I have a quarter circle without core support so to simulate a dent (using symmetry). So...
