Abstract
We consider a model of elastodynamics with fracture evolution, based on
energy-dissipation balance and a maximal dissipation condition. We prove an existence
result in the case of planar elasticity with a free crack path, where the maximal dissipation
condition is satisfied among suitably regular competitor cracks.
