Standard commercial glycerin soap was penetrated using 6 mm steel spheres. The impact velocities (VU) varied from 240 to 1700 m/s. The velocity of sphere within the soap (v), resistance force (F), cavity in soap (Z), and the maximal cavity diameter (D) were evaluated. Within the range of impact velocities used, the following functions have been determined F = a v2 X = b Vun, and D = c + d Vu Based on experimental evidence, the values a, b, c, d and n have been determined.
