hydtools, I was more interested in something more specific with the mathematical modelling of damage in materials, such as fracture, fatigue, etc, ex: Lamaitre and/or Chaboche models. Not in the field of forensics itself, but thanks for the tip. Anyone could help?

Hello everyone, I don't know if I'm posting this in the right place, but here it goes: Does anybody knows any Damage Mechanics course (online, preferably)? Apart from books (whivh I have read a little bit) I would like some good lessons on it. Thanks in advance

Thanks for the anwser, FEA way and GreenElmo! Wow, it seems like a lot of trouble to do that everytime I need to simulate crack propagation, specially if the geometry is complex. Have any of you tried Tie Constraint? The refined region to be the slave one and the coarser region to be the...

Hello everyone, I would like to know how to make a mesh like the one the figure for crack propagation. It is very used in several research pappers and in the book of T.L. Anderson (Fracture Mechanics) it is called Cell Mesh, but I could not find any tips on how to perform it on Abaqus. The...

Any ideas on how to perform that which is not manually?

Would there be a way to calculate J-Integral by using the History Output results? If so, how could I proceed that?

I tried and got this error message: ***ERROR: THIS KEYWORD IS NOT AVAILABLE IN Abaqus/Explicit LINE IMAGE: *contourintegral, crackname=H-OUTPUT-3_CRACK-1, frequency=0, normal, contours=6, cracktipnodes ***NOTE: DUE TO AN INPUT ERROR THE ANALYSIS PRE-PROCESSOR HAS BEEN UNABLE TO...

I tried that, FEA way, but it only allows me to select vertices and points when it comes to define the crack tip region (see print attached). What am I doing wrong?https://files.engineering.com/getfile.aspx?folder=136e4b56-666c-4a97-8143-79bd9f9005a4&file=Sem_título.jpg

Hi FEA way That would work only for a seam crack, i.e., a sharp crack with front defined as a line or point. As I explained, I am trying to make a more "real" crack front considering it a non-sharp (blunt) crack. For that, I do not know how to proceed. If anyone could give me some help, I'd...

Hello, everyone I am trying to model a C(T) specimen to derive the resistance curve from it. As it can be seen from the figure above, I have modeled it considering a non-sharp crack with crack front defined by the row of elements ahead of the pre-crack tip. The growth is simulated by element...
