Abaqus concrete subjected to blast, strain rate

Abaqus concrete subjected to blast, strain rate

Abaqus concrete subjected to blast, strain rate

(OP)
Hi,
Before my study, I want to verify 2 different experiments of concrete slabs subjected to blast.
The stress-strain curve is dependent on strain rate, and i find different rates in different articles.
ponder
How can I tell the right value for strain rate in order to verify the results of those experiments?

RE: Abaqus concrete subjected to blast, strain rate

So you want to compare the results from physical tests to stress-strain curves found in scientific articles but aren't sure which one to choose because they were obtained for different strain rates and you don't know the strain rate occuring in your experiments, right ? If that's the case then you might have to run the simulation first - recreate the experiments in Abaqus, check strain rate available as analysis output and then compare with articles.

Hi
It is not the case.
In the article I want to verify there are no stress-strain curves, only material properties, deflection-time curve and pressure-time curve.
