Abstract
Topological defects in a foam, either isolated (disclinations and dislocations) or in pairs, affect
the energy and stress, and play an important role in foam deformation. Surface Evolver
simulations were performed on large finite clusters of bubbles. These allow us to evaluate the
effect of the topology of the defects, and the distance between defects, on the energy and
pressure of foam clusters of different sizes. The energy of such defects follows trends similar to
known analytical results for a continuous medium.
