This paper investigates the effect of strain rate on plastic anisotropy of advanced high

strength steel sheets at static and intermediate strain rates. Uniaxial tensile tests were performed

at different strain rates to obtain yield stresses and r-values at various loading

angles to the reference rolling direction on two advanced high strength steel sheets of

TRIP590 and DP780 and a conventional cold-rolled steel sheet of SPCC for comparison. A

new method was proposed to measure r-values at intermediate strain rates with the aid

of digital image correlation to investigate the deformation history during tensile tests. Plastic

anisotropy of the steels was modeled with Hill48, Yld89 and Yld2000-2d yield functions

at strain rates between 0.001 s-1 and 100 s-1. The performance of the three yield criteria

was evaluated by comparisons of theoretically calculated planar distributions of the uniaxial

yield stress and the r-value with experimental data. Yld2000-2d yield function was

found to accurately describe the in-plane anisotropy of the uniaxial yield stress and the

r-value of the advanced high strength steels since it has great flexibility due to a larger

number of the mechanical parameters incorporated than that of Hill48 yield function with

which the anisotropy of SPCC can be described acceptably. Yld2000-2d yield loci were constructed

on the two advanced high strength steel sheets and SPCC in order to investigate

the effect of the strain rate on their plastic anisotropy at the given range of strain rates.

For the materials that we investigated, it is evident that strain rate has a distinct effect both

on the shape and magnitude of the yield surface, and the plastic anisotropy tends to diminish

at a higher strain rate.
