Observations of rich LMC clusters reveal an increasing spread in core radius with increasing age. We use N-body simulations of clusters on elliptical orbits about the LMC to show that a time-varying tidal field can result in significant core expansion. The observed spread in core radii may therefore reflect a spread in orbital parameters between clusters.
