Engineered Cementitious Composites material - con_ecc

The con_ecc is a uniaxial generic material modelling the behaviour of ductile fiber-reinforced cement-based composites as described by Han et al. [2003]. The model  needs 13 variables for its definition.

Cracking stress - στ,0
The default value is 2 MPa.

Cracking strain - εt,0
The default value is 0.00015mm/mm.

Peak tensile stress -σt,p
The default value is 2.5 MPa.

Strain at peak tensile stress εt,p-
The default value is 0.03 mm/mm.

Ultimate tensile strain εt,u-
The default value is 0.06 mm/mm.

Compressive strength σc,p-
The default value is 70 MPa.

Strain at compressive strength -ε_c,p^-
The default value is 0.00525.mm/mm.

Ultimate compressive strain -ε_c,u⁺
The default value is 0.03.mm/mm.

Power for tensile unloading curve at-
The default value is 5.

Power for compressive unloading curve ac
The default value is 2

Factor for tensile unloading curve bt-
The default value is 0.4.

Factor for compressive unloading curve bc-
The default value is 0.3.

Specific weight -
This is the specific weight of the material. The default value is 24 kN/m3.
