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

[Anonymous]

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
** Reached autotm limit.

What am I doing wrong?

constant C0 get from Help

constants A1-A4, k0 from "Constitutive model for Slurry Infiltrated Fiber Concrete under triaxial compression" p4

What am I doing wrong?

What uints are you using.  Firstly, the density does not make sense.
