The energy release rate (ERR) is a critical concept in fracture mechanics used to characterize the energetics of crack propagation in materials. It quantifies the rate at which mechanical energy is released as a crack extends in a material. The ERR is especially important for understanding the stability of cracks and the conditions under which they will propagate.
