Impact of anisotropy and viscosity to model the mechanical behavior of Ti–6Al–4V alloy
V Tuninetti, AM Habraken - Materials Science and Engineering: A, 2014 - Elsevier
This paper compares the predictions of an isotropic thermo-elasto-viscoplastic approach
and of an anisotropic thermo-elastoplastic one with experimental results representative of
the mechanical behavior of Ti–6Al–4V at moderate temperatures and low strain rates. The
first model is the well known Norton–Hoff viscoplastic constitutive law with isotropic von
Mises yield locus identified by using monotonic tension tests performed at strain rates from
10− 3 s− 1 to 10− 1 s− 1 and at temperatures up to 400° C. The second model is a thermo …
