Figure 4 shows the plots of the force impulse duration as a function of five parameters mentioned above. The plots were constructed for parameters that varied within the following limits: mass from 0.05 kg. to 10 kg; radius of the striker from 5 mm to 140 mm, the velocity of the striker from 0.05 m/s to 10 m/s; modulus of elasticity of the gasket from 0.2 GPa to 200 GPa; the thickness of the gasket from 0.1 mm to 50 mm. It should be noted that for all curves presented in the figure one of the five specified parameters was allowed to vary within the specified limits, and the remaining four corresponded to the reference values: the striker mass was 4 kg, the striker radius was 4 mm, the striker velocity was 1 m/s, the modulus of the gasket was 10 9 Pa, the thickness of the gasket was 2mm. At these values of the parameters, the calculated impulse duration was 1.04   ms (this value was marked by a dot on the curves in Fig. 3).
