27.4. Material Properties

The model uses structural steel with elastoplastic behavior. A bilinear isotropic hardening material model (TB,PLASTIC,,,,BISO) is used with the following temperature-independent material properties:

Material Properties for Hot-Rolling Analysis
Young's Modulus 200 Gpa
Poisson's Ratio 0.3
Tangent Modulus 2 Gpa
Yield Stress 70 Mpa[a]
Coefficient of friction [b] 0.6

[a] A hot-rolling problem uses a low-yield stress value.

[b] Between rollers and block during the rolling process.
