It is based on a standard isotropic quasi-static damage law which is extended with damaged viscoelasticity and retarded damage to consider the physical mechanisms of strain-rate sensitivity.
Cumulative damage laws, including the classical Linear Cumulative Damage law (LCD), are introduced to enlighten these comparisons.
Those parameters are incorporated into a material model following the Lemaitre damage law.
In addition, the frictional behavior is analyzed using a form of Kachanov-type damage law.
To the classical set of GTN parameters corresponds a set of damage parameters for Lemaitre's damage law.
This work faces the challenge to apply a progressive damage law for oblique fracture planes.
The creep rupture life of the smooth specimen was successfully predicted by the classical Kachanov Rabotnov damage law.
A bilinear damage law came out to be necessary to match the experimental behavior of the nanomodified interface, while the virgin material can be represented through a simple linear damage law.
The damage law is identified by means of in situ tensile tests performed inside the scanning electronic microscope.
The approach is first qualified by using displacement fields resulting from a non-linear computation with a known damage law.
A new strain field related cohesive damage law is introduced to describe the behaviour at the crack tip.
