Abstract
A dynamic constitutive equation of simple form was
presented. Series of experiments were conducted for various types of materials
to verify the proposed equation. From the investigation of experimental data it
was confirmed that materials could be resolved into various groups according to
different dependence of strain rate sensitivity on flow stress and also
inelastic strain. Comparison between experimental data and numerical
simulations concluded that the equation well predicted the flow stress in the
strain rate range of 10-4 to 105/s-1,
temperature range of up to 713K, provided that a quasistatic stress-strain
curve at a reference temperature only was given.
