Abstract We investigate the dynamics of cracking of a brittle coating covering an elastically stretched substrate. We consider here a scalar model (an electrical analogue) in order to describe fractures in thin and in thick films. The model captures the essential features of the fragmentation of coatings and allows us to classify different temporal regimes in the cracking process and to obtain several basic patterns of the cracks' morphology.
