Thank you guys, this is going to be very useful.
I have also seen that there is no enrichment with singular fields at the crack tips in Abaqus.
This means that tha crack has to cross completely an element at each increment.
I will work on your documents and come back to you if I have additional...
Hi there,
I am trying to model a quasistatic crack propagation in a solid subjected to bending.
I have inserted a precrack and defined a MaxPs traction separation law for the cracked domain.
I don't understand how Abaqus deals with the crack propagation !
At the beginning, the stress increases...
OK I found how to import the deformed mesh as well as the stress field.
You have to be careful because Abaqus add a "-1" extension to the part you import, and the name of the part does not correspond anymore to the one of the .odb file that you have imported.
You thus have to delete this "-1"...
The thing is the parts are loaded without any crack at the beginning.
Once the stress induced by the thermal cooling has reached a certain critical value, a crack initiates and propagates dynamically.
Now, I need to import a stress field (or temperature field), but also the deformed geometry...
Hi there,
I have performed a coupled temp-displacement analysis to simulate the cooling stage of two bodies in contact.
Due to the thermal expansion mismatch, a stress tensile stress field appears in one of the two bodies.
Now I would like to study how a crack would initiate and propagate in...
Thank you for your answer Corus,
I will use the Temp-Displ analysis.
I just need to find physical values for gap conductance properties between Silicon and Epoxy. Such data are always difficult to find in the literature!
When the two bodies are in contact, there is no real gap between them...
Hi everybody,
I would like to model the cooling operation of two bodies sticked together and with two distincts expansion coefficient.
I would like to observe the stress concentration appearing due to the difference in terms of expansion coefficient.
I have some difficulties to build the case...
