Generally, the stress wave method is based on the propagation of the waves inside the solids
which under some conditions cause the material to undergo the necking phenomenon. The
numerical method by the way needs to employ dynamic explicit solver to be able to show the
necking phenomenon. However, the most important step regarding the solutions in this method
is to give applicable material properties to obtain the acceptable results for the time and the
place of the necking. Therefore, the material properties implemented to the numerical model
should be modified specifically for the points after the necking. This study compares some of
the correction methods affecting the necking time and shows that without suitable correction
factor, the explicit solver will not be able to define the necking appropriately.
