Computational modeling of hip implants 401
simulated with a cohesive failure model (Maiti and Geubelle, 2005), using
the classical Paris failure curve between the crack advance per cycle and
the range of applied stress intensity factor. A cohesive zone law has also
been developed for predicting fatigue damage of adhesively bonded joints
(Khoramishad et al ., 2010). A mixed-mode bilinear traction-separation law
was considered for joints between thick sheets of 7075-T6 aluminum alloy,
bonded to each other with a toughened epoxy lm adhesive. The failure
behavior of the epoxy lm adhesive was described with a cohesive zone
law. Intergranular fatigue damage in rolling contacts has additionally been
described with a cohesive zone law (Slack ...
