Strain Rate Effect

Post by aufdc » Tue Jul 05, 2016 4:36 am

Hi fmk,

Now I'm working on the concrete material model including strain rate effect, I just wonder that will the strain rate be computed in the element level (especial for beam elements) or not? I know that for truss element and zerolength element, the strain rate will be compute. I have seen in Concrete02 the strain rate equals zero, but I'm not sure beam element will compute it or not.

Thanks!

no strain rate is computed by the beams or sections for passing to the materials .. you will have to compute yourself from the strains .. you can get the time step from OPS_Dt global variable (defined in OPS_Globals.h)
