Abstract
On the basis of simple one-dimensional finite element analyses, compar ison in simulations of uniaxial tension using explicit dynamic and imp licit static tonnulations has been made. Results show that for materia ls having a Hollomon-type constitutive law with power-law strain rate sensitivity, the explicit dynamic method can be employed for the quasi static simulations of tensile tests only below the critical test veloc ities or critical normalized material densities. These critical values are determined numerically as a function of material parameters.
