Cohesive Models
of Fracture
Organized
by W. Brocks
Introducing
a cohesive zone ahead of a crack tip where the micromechanical processes of
separation occur, is a classical approach in fracture mechanics. Together with
the growing importance of numerical simulations in materials mechanics and the
rising capabilities of computers and computer codes, cohesive models have found
increasing interest and applications. They have not only become versatile and
effective tools for numerical simulations of various separation phenomena in
solids but also reveal new potentialities for advanced material
characterization. Quantities which have been unmeasurable
in the past, as e.g. separation energy in ductile tearing, may now be
quantified within the framework of these models by combined testing und
numerical simulation. The minisymposium on cohesive
models will compile, collect and discuss the present state of the art as well
as future developments and challanges. Contributions
to any kind of cohesive modelling, e.g. ductile crack
growth and rupture, creep damage and fracture, dynamic crack propagation,
fatigue, interface decohesion etc., on various size
scales will be addressed.
