ABSTRACT

The longitudinal impact of a rigid body on a flexible rod is theoretically investigated. The

mathematical model is numerically solved by the method of characteristics. The boundary

conditions at the contact end are fully discussed. A new treatment for the contact end is then

developed without using any non-physical conditions. Boundaries of both Venant and present are

applied to the main numerical solution. The results of the two solutions are discussed and

compared with available published experimental measurements. The results of both experimental

and Venant’s are characterized by the shape of pulse propagation. The proposed solution is

successfully simulated the physical wave propagation. The rebound velocity is accurately

calculated. All parameters variation prove the behavior of the continuous media mode

characterized by the wave propagation.
