G'day all
Having a metal element with a notch like crack (assume sharp one, exhibits plasticity), what are the actual fracture mechanism (the phases the crack goes through) in the total fatigue-life.
please comment on these scenarios:
1- crack initiation life calculated from the (S-N, e-N), then using LEFM/EPFM to determine the cycles for the crack propagation to failure...
Q/ how to find the crack length between the two phases, I mean from which stresses and at which crack length we start the crack propagation life estimation.
WCFA workshop on Design and Fatigue of Weldments
This is the second announcement about the upcoming Workshop on Computational Fatigue Analysis 2017, this year dedicated to Design and Fatigue of Weldments (WCFA2017-DFW - http://www.pragtic.com/DFW.php). The workshop is held in Prague, Czech Republic in November 13-16, 2017. The key lecturer, who guides the audience through various issues of the fatigue analysis in welds, is Dr Zuheir Barsoum from KTH - Royal Institute of Technology in Sweden.

Nonlinear dynamics of rotating shaft with a breathing crack - CHINA SCHOLARSHIP COUNCIL PhD for 2017
Because of the increasing need of energy, the plants installed by electricity supply utilities throughout the world are becoming larger and more highly stressed. Thus, the risk of turbogenerator shaft cracking is increasing also. The development and propagation of a crack represents the most common and trivial beginning of integrity losses in engineering structures.
Fatigue crack propagation

Hi, I'm trying to perform a supposedly-simple experiment on fatigue crack propagation of UHMWPE. I use a compact-tension specimen on a servopulser hidraulic testing machine. I will try to do the experiment on a fix Pmax with a varied force ratio (R) from 0.1 to 0.5. I'm having trouble in deciding the maximum force Pmax. How does one decide the amount of force applied for FCP testing? Calculation steps and so on.
crack propagation in Abaqus (VCCT) with remeshing
Forums
I started using VCCT with quarter tip elements in Abaqus (not XFEM). I can solve the problem and get the SIFs.
How can I let the crack grow? Has someone a script for crack growth and remeshing that I can implement?
Modeling with line spring elements to find failure pressure of steam generator tube

Hello, All
I am trying to model steam generator tube of length 110 , radius 11mm, thickness 1.27mm. It has 2 axial cracks of length 6.35mm. length between 2 cracks is 0.254mm.
As line spring elements cannot be created using Graphical user interface I first need input file. So I modelled the tube with shell elements S8R without any crack (once this model will run I will get input file and can modify it). As per paper which I am following the fracture coalescence pressure is 60Mpa means at this pressure J integral exceed the critical JIc.
