Abstract We present a one-dimensional time-dependent numerical model for the expansion process of ablation plasma induced by intense pulsed ion beam (IPIB). The evolutions of density, velocity, temperature, and pressure of the ablation plasma of the aluminium target are obtained. The numerical results are well in agreement with the relative experimental data. It is shown that the expansion process of ablation plasma induced by IPIB includes strongly nonlinear effects and that shock waves appear during the propagation of the ablation plasma.
