Researchers have developed a simplified mathematical model (step-loading model, SLM) that unifies two earlier mechanisms to describe the velocity jump in crack propagation. Through SLM, they showed that the near-tip mechanical behavior observed from one analysis is derived from the dynamic glass transition at the crack tip described in another proposal, thus merging the two distinct analyses, and demonstrating that the velocity jump occurs in many materials.
