An analysis is here presented of the large plastic deformations of a beam under impact such as that due to a blow of a massive hammer, in which one cross-section is suddenly forced to move with a given velocity. The analysis treats both the case in which the velocity of the struck section is maintained constant until the total permanent deformation is acquired and cases of interrupted impacts in which the force at the struck section is suddenly removed after an arbitrary contact time. A complete solution in general bob-dimensional form is obtained in a simple manner by basing the analysis on the assumption of plastic rigid behavior, an results can be expected to be valid when the plastic deformations are large enough. Criteria, for the validity of the present results are discussed, based on the mojor assumptions of the analysis.
