I am required to model cracks in ABAQUS, and I am using a smeared cracking model. I have already introduced the model plasticity to my model and have been successful in running the model so far with no set-backs.
One thing I am unaware/unsure of is the cracking part. Although I have introduced a ramp force that is applied with each step increment, my model doesn't seem to be cracking. Are there any more steps to be taken after introducing the model plasticity? All the regular steps required for analysis have been performed.
P.S- I am new to modelling cracks and started ABAQUS few months ago
best,
Dear Usman,
First you try to put damage criteria. In abaqus the simplest way is use Johnson cook damage criteria, use displacement value for element deletion. Start from minimum value. You will see crack propagation through the element deletion. Please contact if you need any other help.
Thanks
Vivek
Dear Vivek,
Thankyou for your reply,..I just checked the Abaqus manual. Isn't the Johnson Cook Damage criteria only for metals? or can it be applied to the concrete as well?
Thanks!
Sorry for the delayed answer,
I am employing a non-linear analysis using a smeared cracking model in Abaqus Standard
sir i am modelling rcc slab in abaqus and i want to propogate cracks in the same.can you help me how to do??
