The investigations carried out are dedicated to the analysis of the material impact of the loading environment upon the effectiveness of a shock pulse at wave deformation strengthening. To carry out investigations in the specialized program there is developed a finite-element model of an impact system consisting of a head and a waveguide pressed statically to the environment of loading. The impact system effectiveness was estimated on the ratio of shock pulse energy imparted to a deformation source taking into account the material of the loading environment to the energy of a head blow to a waveguide. It is defined that the most significant impact upon a share of transient energy of the shock pulse is rendered by the head parameters the change of which in the range considered allows increasing the effectiveness of the impact system by 15.6 times. The next important factor affecting considerably the effectiveness of shock pulse energy transfer is a ratio of the lengths of a head and a waveguide the change of which in the value range investigated allows increasing a share of energy transferred by 2.8 times. The least impact upon the effectiveness of impact energy transfer in the center of deformation with the impact system is performed by the material of loading environment – 1…3% for the rational values of the parameter ratios of the impact system elements (n more than 80%). At the forced choice of less efficient impact systems (L1/d1=1 ; L1/L2=1…10; n less than 62%) the impact of the material of loading environment may make 6…10%.
