Abstract: | The impact energy decay in a step-up chain containing two sections is numerically studied. There is a marked biphasic behavior of energy decay in the first section. Two sections close to the interface are in compression state. The degree of compression of the first section first decreases and becomes weakest at “crossing” time of biphasic behavior of energy, then increases. The further calculations provide the dependence of the character time on mass ratio (m1/m2), where m1 and m2 are the particle mass in the first and second section respectively. The bigger the α (α =(Ωm1-m2)/(Ωm1+m2)]2 with Ω =1.345), the bigger the energy ratio is. The multipulse structure restricts the transport of energy. |
