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

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? Regards Ash

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...

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?
