Abstract :

Impact loading of free-free beam is of high interest to researchers as well as industry application. In this article a free-free beam subjected to concentrated impact loading is considered. Beam material is considered to be a rigid perfect plastic. Different combinations of loads, energy absorption and load location are considered. The result of the analysis show that when the load is less than critical load, the beam acts as a rigid body and when the load is greater than critical load three different mechanisms prevail. The result of the experiment is compared with analytical as well as simulation process using ABAQUS. The results of the compression are in good agreement with experimental investigation.
