Abstract Scope |
the present work aims to predict mechanical behavior of an industrial rolled sheet for a DIN 1623 St14 (DC04) steel via numerical model, based on the plastic anisotropy. First, an experimental device of simple tensile tests, in several directions relative to the rolling direction, and the studied material are described. Second, the modeled and simulated results behaviour under Hill1948 quadratic formalism yield criteria and FEM Method are compared. Finally, an heterogeneity of the properties is well recorded through the analysis of the stress-strain curves obtained via modeling, as well as for the yield stresses and Lankford r-values in uniaxial tensile test. However, the influence of “r-values” upon the Yield locus shape defined by the above comparison is well highlighted. |
