Application of failure criteria to viscoelastic materials

Click For Summary
SUMMARY

Failure criteria for viscoelastic materials, particularly in the context of viscoelastic composites like human tissue, involve understanding how these materials respond to stress over time. Unlike brittle and ductile materials, viscoelastic materials exhibit time-dependent strain, requiring specific criteria for failure analysis. Key methods include the use of the Prandtl-Reuss equations and the viscoelastic constitutive models to predict failure under various loading conditions. The discussion emphasizes the importance of researching established failure criteria specific to viscoelastic materials for accurate assessments.

TL;DR
Failure criteria of viscoelastic materials.
I was wondering if someone can explain how failure criteria work when dealing with viscoelastic materials.
I'm quite new to this, so I only know how they work with brittle and ductile materials. (not in too much detail either).

And now that I'm at it anyway, if possible an explanation on failure criteria with respect to viscoelastic composites
(human tissue in specific) would be great :)
