Debonding of the stem–cement interface and damage accumulation in the cement mantle
are basic events that contribute to the long-term failure of cemented hip reconstructions. In
this work, a numerical study with these two processes coupled is presented. On the one
hand, debonding of the stem–cement interface was simulated by means of a cohesive
surface theory that was implemented into an interface finite element. This interface model
includes a tensile-shear behavior law, the fatigue failure of the interface, and the friction …
