Crack Initiation in Viscoelastic Materials [PDF]
Physical Review Letters, 2018 In viscoelastic materials, individually short-lived bonds collectively result in a mechanical resistance which is long-lived but finite, as ultimately cracks appear. Here we provide a microscopic mechanism by which cracks emerge from the nonlinear local bond dynamics.
