hi,Jan
Thanks for your suggestions. The model in PFC is parallel bond model and I
think the difference is that in parallel bond model its moment is contributing

sorry, haven't noticed this. For sure, 0.9 is too little (not too high)

Hi, Jane

especially when the relductivity is large (eg.over 10). so when the value

in the model design, relDuctility should affect the softening behavior :-)
If it only affects the hardening, then th
