The effect of immersion in a non-swelling liquid under pressure on time-dependent crack growth has been studied for various elastomers. A large effect of pressure is observed, with the rate of growth decreasing by approaching three orders of magnitude per kbar. It appears that the effect is mainly associated with the change in glass transition temperature although other factors may also be involved, such as the tendency of the failing material at the tip to separate into filaments. Measurements of strains at the crack tip suggest that this tendency may be associated with the presence of stresses through the thickness of the material.
