Harmonic analysis with a crack?

Choose a channel featured in the header of iMechanica: 

Hello everybody,

                          I am trying to perform a harmonic analysis of a material sample (say a simple 2D plate) with an edge crack in it using 'Ansys R16'. I see that under sinusoidal loading condition, the two crack faces open or close and interpenetrate (after closing which is not possible practically).

          1.  I believe, stiffnesses of the crack faces change during interpenetration and so the results are not credible anymore.

How to extend crack in Mixed mode crack growth in Ansys ?

Hi, I am doing project on mixed mode crack growth of semi elliptical crack in gas turbine components under cyclic loading. Ansys has capability for finding J,K using CINT command. But, In mixed mode crack growth, i dont know how to deal with nodes and how to create random crack with new node coordinates obtained from previous steps. If you have any ansys code related to creating crack and finding fracture parameters like K, J (mode 1 or mixed mode), Can you please give me the code.

Thanks

(I cant use any other software, only Ansys)

Can any one provide any apdl code to perform automatic fatigue crack growth ??

Hi, I am using Ansys Apdl for 3d fatigue crack growth. I need any one code to understand how it can be automized (recreating crack with node shift and remeshing).

 

Thank you

Hello ALL,

Any sort of help related 3d fracture analysis.

 Thanks
