  Shrimali and Lopez-Pamies (2023) have recently shown that the Griffith
criticality condition that governs crack growth in viscoelastic elastomers can
be reduced to a fundamental form that involves exclusively the intrinsic
fracture energy $G_c$ of the elastomer and, in so doing, they have brought
resolution to the complete description of the historically elusive notion of
critical tearing energy $T_c$. The purpose of this paper -- which can be viewed
as the third installment of the series started by Shrimali and Lopez-Pamies
(2023) -- is to make use of this fundamental form to explain one of the most
popular fracture tests for probing the growth of cracks in viscoelastic
elastomers, the trousers test.
