Review: fatigue of hydrogels

Here is our review article on fatigue of hydrogels. This is the first review of the subject. We review fatigue as any failure of material under prolonged static or cyclic loads. The paper starts with fundamentals, and covers a broad field, yet leaving a lot of interesting questions to be answered. The paper links the chemistry and mechanics of hydrogels.

The publisher now provides 50 days’ free access to the paper.

Fatigue Fracture of Self-Recovery Hydrogels

Dear Colleagues,

Here is our recent paper “Fatigue Fracture of Self-Recovery Hydrogels”. To the hydrogel community, this paper distinguishes the fatigue fracture and the self-recovery of a hydrogel. To the mechanics community, we show that, for the first time in hydrogels, the fatigue threshold depends only on the covalent network, but not on the noncovalent interactions that provide dissipation.
