Experimental And Numerical Analysis Of Propagation Of Stress Wave In Sheet Metal

Abstract In this experiment on the propagation of stress waves on sheet metal of different material andtheir effect of casing is studied and reported. Steel and aluminum are the two different types of materials which are considered and instrumented with the strain gauges. Metal foil gauges are most commonly used to measure the strain accurately. It is then externally impacted by the ball pane. The output that is obtained is in the wave form and is stored in the oscilloscope. The stress waves are induced in sheet metal due to the impact of ball pane. The amplitudes of stress waves which are obtained from the oscilloscope are studied and to determine the velocity of stress wave propagation and damping capacity of the material. Propagation of stress waves are obtained from the experimental and numerical methods are then compared it with the analytical methods.
