Can anyone advise by your experience, which is the best software for crack propagation problems?
That is; calculation of stress intensity factors using linear elastic fracture mechanics or elasto plastic fracture mechanics. Computationally effective with good manual (user guide examples) ?
Thanks
My Y rotation on nodes B and E was fixed. It otherwise reported instability error if ever I left the Y rotation free
I don't get that. I just released the X rotation and made the condensed stiffness matrix. Yes, it had 0's in the corresponding rows and columns
Yes, as I said above
Yes, X is parallel to AB
You said
Will it not be the same if I have no coincident nodes but a hinge (to release X rotation) at the location of the coincident node?
This is a very simple problem using which I'm trying to validate my finite element code
I have two plates Plate 1 and Plate 2.
Plate 1
In this plate I connected elements ABEG and BCDF
Nodes E and F are co-incident
I connected E and F by rigid elements. I did NOT connect E and F for rotation...
I have a cantilever column of length 1m.
I have applied a lateral load of 200 kN uniformly distributed over the length of the column
I have carried out a geometric non linear analysis and see that the (maximum deformed) statistics are as follows:
-314.40 mm(translation X)
0.00...

I have used Newmark's method wherein my damping matrix was generated through a combination of mass and stiffness matrix (Rayleigh damping).
IS it possible to use the Newmark's method if the damping matrix is non diagonal?

Hi,
I have been trying to interpret the physical reason of this clause in DNV2013.
Link
See link below Clause 606 equation 5.25.
It calls for a reduction in the plastic moment capacity if the structural element has lateral point loads.
I personally feel the reason for this clause is to...
Hi,
I know that one gets complex Eigen values when there is damping in the system. IS it possible that if the system is unstable, one gets complex values?
I have got a structural system wherein I get complex Eigen values. The system is undamped.IT is stable.
I would like to understand the...
msquared48;
Why do you say "yes" if the crack is along the same diagonal was present on both sides of the window?
I'm not able to understand why you say "yes"?
I'm sorry but I shall be happy if anyone can help me.
IS it true, that if there is a crack near a window, then structurally, the length of the crack = actual length of the crack + length of the diagonal of the window.
I'm not sure, if / how this is true?
