Concrete02 Material -- Linear Tension Softening
| uniaxialMaterial Concrete02 $matTag $fpc $epsc0 $fpcu $epsU $lambda $ft $Ets |
| $matTag | integer tag identifying material |
| $fpc | concrete compressive strength at 28 days (compression is negative)* |
| $epsc0 | concrete strain at maximum strength* |
| $fpcu | concrete crushing strength * |
| $epsU | concrete strain at crushing strength* |
| $lambda | ratio between unloading slope at $epscu and initial slope |
| $ft | tensile strength |
| $Ets | tension softening stiffness (absolute value) (slope of the linear tension softening branch) |
NOTE:
- Compressive concrete parameters should be input as negative values.
- The initial slope for this model is (2*$fpc/$epsc0)
