Compressive strength of cohesive element
Compressive strength of cohesive element
(OP)
Hi,
is it possible to assign traction compressive strength to cohesive layer?
I have assigned Traction Separation response and material. But this is only for tension adn shear strength. Is it possible to add compressive strength?
Thanks

Check the users manual if you want to know what material model has what damage options.

I was searching through the materials that Abaqus has, but I haven't found one like this. Maybe you have advise me better?

1. Elastic material/suboption Fail stress. But I don't want to define tension stress. As I have read this option is mentioned for fiber reinforced materials. I am not sure will it work, I will try.
2. Hashin damage. Similar case like first option (if I don't define tension and shear strength). But these strengths are for longitudinal direction, so here the situation is little bit more complicated.
3. Concrete smeared cracking, using failure ratios.
What do you think about selection?
Or I should take other approach, since I have modelled tension and shear with cohesive element, maybe there is easier way just to add compressive strength until some value? Maybe with yero length spring or connector?
