This phenomena is also the subject of studies related to composite materials due to fact that composites are widely used as an energy absorbers in road safety structures [6].
One of the most important factors in preparation of the analysis is to select a suitable material model to allow for the effects of strain rate on the changes in material properties.
One of the material models allowing for the effects of strain rate is the model developed by G.R.
A simplified Johnson-Cook model was used as a material model with the material parameters determined based on the strength tests [4].
