The equations of Szendrei/Held for the radial crater growing process as a function of time can also be inverted to get the target strength R t if the maximum crater radius r cm is known. With this method the strength was calculated for an aluminum target to 300 N/mm 2 and for glass fiber reinforced plastic to 405 N/mm 2 , which are at least very reasonable values. By using these values for R t , the comparison of the radial crater growth process with carefully arranged and analysed experiments by the Ioffe Institute is showing good agreements.
