Energy release rate calculations are performed for a flexible strip peeling from a substrate and including the effects of kinetic energy. The effects of various wave speeds are demonstrated. Solutions for an axially loaded strip are then explored, including the transient solutions and those for steady-state conditions. The methods developed are then used for cases involving the bending of strips, including those of moving loads. It is demonstrated that these methods of analysis are of value in the analysis of test specimens and of use in design.
