My personal guess is that one studying the stability of dynamic explicit simulation has to distinguish two things :
1. The calculated stable time increment, that depends on mesh condition, materials constants such as density, elastic constants, and then the characteristic speed wave.
2. The...
Hi all,
Here is what SIMULIA customers help says.
Q :
In an Abaqus/Explicit analysis, is the loading taken into account in the calculation of the stable time increment?
A :
(The following applies to any version.)
No, loading and/or load type is not directly considered in the calculation...
Thank you much for your quick reply !
Okay, so if I understand, the time increment has to be small enough in the sense that a shockwave shouldn't have time to cross that element more than once during an incrementation.
It's indeed clearer. Though, about the effect of boundary conditions on the...
Dear all,
Here is a question(s) about the stability criterion in a dynamic explicit analysis.
In ABAQUS user's manual I red that the stability of an explicit procedure can be ensured if the time-increment is small enough. Then, as a limit criterion of stability, the given time-increment should...
