Yiled theory coefficients?
Can anyone plz send me instructions on how to calculate the coefficients a,b,c,d,h (f,g = 1) for YLD91 and subsequent ones? I have a rough idea, but if someone has explicit instructions ..

Fatigue life calculation - reporting stress
For fatigue life estimation (HCF & LCF), I am not sure which stress shall I consider i.e. max. principal stress or von Mises stress & what should be the criteria for selection of the same? Shall we be driven by material model (i.e. ductile or brittle) or mode of failure or some thing else?
infinite finite elements
Hello, does anyone know where I can find more information about the infinite finite element or way to couple BEM/FEM to solve the problem in infinite 3D domain? Moreover, what is the difference between using a very long/large finite element and an infinite element? Many thanks...

How to get residual stress, Given HV--True Strain Curve and HV--Position from the surface Curve?
Hi, Everyone,
I have done an experiment, and got the HV(microhardness)--True strain curve, and the Cuver of HV(microhardness)--Position from the sample surface.
Now I want to know how to compute Residual stress? according to the the upper information.
It would be very kind of you to give any suggestions. Thanks in advance.
Best Regards

Not converged for modelling crack propagation
Hello! I am modelling crack propagation in concrete specimen under direct tension by using cohesive element in ABAQUS as the interface where crack will propagate. By setting up the proper values of the parameters, I could model the exact behavior prior to the cracking, however, when changing some parameters to get the interface cracked, the model committed to be diversed. I have tried some little skills like viscosity and energy disspation fraction, but it was still not working.
