Abstract This article gives a brief review of recent progress in the theoretical description of electron and ion dynamics following strong excitations of a metal cluster. Intense femtosecond laser pulses and collisions with highly charged ions are considered typical examples for those violent excitation mechanisms. The theoretical tool is time-dependent local-density approximation (TDLDA) complemented by local pseudopotentials and occasionally explicit ionic motion (in terms of classical particles). We discuss the distribution of the initial excitation energy over collective plasmon oscillations, ionization, and internal thermalization. Relevant time scales for the dynamical evolution are evaluated and compared.
