| description | As found by experiments quasi rate independent materials (QRI) describe very
well behavior of steels in very wide range of strains and strain rates
([3],[4]). This property has been combined with tensor representation
modeling using a generalized associative flow rule based not on the yield
function but on a more general loading function. Seemingly rate independent
QRI producing incremental evolution equations show rate sensitivity by means
of variability of yield stress with stress rate. On the other hand transverse
isotropy appears in metal forming issues like in rolled car body sheets [18].
Here an extension of tensor generators and invariants is needed to include
the preferred anisotropy direction. Such a procedure has been made here. In
addition we believe that the results of this paper are applicable to dynamic
deformation of orthogneiss rocks treated recently in [5]. |
