A stepped circular bar consists of two lengths L and 3L with respective areas 2A and A, The smaller end strikes a rigid perpendicular target at 12.7 m/s. Plot the location-time diagram showing the magnitudes and direction of the wavefronts for as long as plasticity continues to occur. Plot the residual plastic strain distribution. Assume the following: E = 207 GPa, aa = 345 MPa, S = E/16 and p= 7890 kg/m³.
