# Use concrete material in "Static Stress with Nonliner Material Models"

## Use concrete material in "Static Stress with Nonliner Material Models"

(OP)
Hi.
Did anybody use reinforced-concrete material in NonLinear problem in Algor 2012?
Material settings:
** Plain concrete material properties

Young's modulus =  0.3250E+05
Poisson's ratio =  0.1800E+00
Mass density =  0.2447E-12
Failure strength in uniaxial tension =  0.1150E+01
Failure strength in uniaxial compression =  0.1700E+02
Constant shear retention factor =  0.7000E+00
No tension stiffening is defined
Hardening curve
Plastic Strain          Stress
0.0000E+00      0.0000E+00
NaN              0.1700E+02
Material model parameters
A1 =  0.3300E+00
A2 =  0.9260E+01
A3 =  0.4130E+01
A4 =  0.2400E+00
C0 =  0.5500E+01
k0 =  0.8800E+00

The solver report:
Time        Percent     DT       L Iter. Residual
0.000000   0.00     0.050000  1   0   0.0000E+00
