Cohesive Elements in Abaqus Implicit and Explicit
Cohesive Elements in Abaqus Implicit and Explicit
(OP)
Hello Everyone,
I have recently seen a very strange and interesting challenge through my Abaqus simulation might be exciting for more investigations. We want to model a composite material defamation with Continuum Elements (C3D8R) and Cohesive Element (COH3D8). We have to also implement a pre-tension load in the model based on the practical case.
The problem is following:
Through two simulations with the same model and same material; if you implement a pretensile load on Cohesive Elements:
1- In Abaqus Implicit: the all Cohesive Elements reach all together to the damage initiation point; MAXSCRT=1 (the starting of degradation) just after the first increment
But for:
2- In Abaqus Explicit it works fine and Cohesive Elements reach to this point after a valid number of increments.
For both cases, I have used exactly the same model.
In this case, I would be happy if somebody could let me know if has any relevant experiences or hints.
Thanks in advance,
Best regards
