- •
Post-peak cyclic behavior of concrete in direct tension is studied.
- •
Various loading regimes are performed on concrete in tension.
- •
Strain rate effect on the post-peak stress-strain response is considered.
- •
Stress releases and damage accumulations are independent of strain rate.
- •
Damage constitutive model is proposed to describe the stress-strain relation.
