Strain rate sensitivity of mechanical properties of the ZK60 alloy with the high degree of corrosion damage

Frontier Materials & Technologies, 2023
There is a strong belief that hydrogen absorbed by magnesium alloys during corrosion can cause their stress corrosion cracking. One of the characteristic markers indicating the involvement of diffusible hydrogen into the fracture mechanism of metals is ...

Nonlinear Stress Fluctuation Dynamics of Sheared Disordered Wet Foam

, 2003
Sheared wet foam, which stores elastic energy in bubble deformations, relaxes stress through bubble rearrangements. The intermittency of bubble rearrangements in foam leads to effectively stochastic drops in stress that are followed by periods of elastic

Unified Description of Aging and Rate Effects in Yield of Glassy Solids [PDF]

, 2005
The competing effects of slow structural relaxations (aging) and deformation at constant strain rate on the shear yield stress $\tau^y$ of simple model glasses are examined using molecular simulations. At long times, aging leads to a logarithmic increase
