•Cavitation in micro-spall is modelled using a free-surface approach with multiple bubbles in an incompressible liquid.•When the liquid is pulled outwards, bubbles expand.•All bubbles do not expand at the same rate and some even shrink until collapse.•The number of bubbles “surviving” can be charact...
