Crack propagation with Gurson model
hello
I identified a set of parameters of the Gurson model. How to use these parameters to simulate the propagation of a crack in a CT specimen?. In another way how to simulate the propagation of a crack with the GTN model?
thanks!
Plrase help me for this case

3D phenomenological constitutive modeling of shape memory alloys based on microplane theory
This paper is studied constitutive modeling of SMAs, that have some new features. Also some multiaxial loadings on SMAs are investigated experimentally.
Itasca UDEC 4 - shear ratio (srat)

Hi, everybody!
I have some problem with understanding of shear ratio history (srat) in UDEC.
Here is the description of this function in UDEC manual: "srat - ratio of shear stress to shear strength at contact".
If I take the value 1/srat then I should normally get the value of factor of safety (FS) for shear condition, since this value will be the ratio of shear strength to shear stress at contact. But shear displacement history (sdis) shows that there still can be some shear displacement in case of FS=1/srat more than 1.
