Kink band propagation in fibre composites, buckling-driven delamination of thin films, buckle propagation in undersea pipelines and channelling cracks in layered materials are all examples of propagating instabilities. Although different physics, materials, geometries and loading conditions are involved, similarities in the modelling are addressed and can be utilized for simplifying descriptions of propagation conditions. The simplified approaches utilize the Maxwell conditions assuming path-independence of released energy without the need to study details of the transition front propagating under steady-state conditions.
