Novelty/impact/significance

1.      Analytical formulation of cavitation dynamics in vitrimers;

2.      Prediction of the dependence of the cavitation dynamics of vitrimer on the loading rate;

3.      Investigation of the strain stiffening effects on the cavitation dynamics of vitrimer.

Scientific question

This article studied the cavitation dynamics of vitrimer.

Key of how

In this article, we formulated the cavitation dynamics in vitrimer with considering both exchanging reaction of the dynamic bonds and strain stiffening effects.

Major points

1.      Formulation of cavitation dynamics in vitrimers;

2.      Prediction the dependence of the cavitation dynamics of vitrimer on the loading rate;

Finding of the work

      1. Our calculations have shown that the loading rate can have significant effects on the cavity growth in a vitrimer.

      2. During the cavity expansion, the strain rate in a vitrimer can vary a lot both spatially and temporally.

      3. When the loading rate is high enough, the dynamics of the cavity expansion in a vitrimer is the same as that in a hyperelastic elastomer; when the loading rate is extremely low, the cavity expansion in a vitrimer is the same as that in a Newtonian fluid.
