How to check element strain rate in a dropping simulation?

Hi all,

I want to check the strain rate in my dropping result model to see the strain rate range. However, I cannot find the way to get it. Should I define some keywords to output it?

 

Thank you

Roy

    Hi Roy,

    Please try with /ANIM/ELEM/EPSD for equivalent strain rate in bricks and also in shells.

    Hi George,

    I'll try it. From the manual, it seems that it is only for bricks. In addition, what's the meaning of 'only available in case of strain rate filtering'?

    Hi Roy,

    Equivalent strain rate in bricks and also in shells are available. 

    Because of the numerical application of dynamic loadings, the strain rates cause high frequency vibrations, which are not physical; thus the stress/strain curves look 'noisy'. To obtain smooth results, the strain rate filtering option will allow the reduction of those oscillations by removing the high frequency vibrations.

    Please go through Example 11 - Tensile Test in Help Menu which explains the same.
