Failure of the cement mantle has been identified as a possible
mode of failure of the implanted femur in total hip replacement (THR)
. Finite element (FE) analyses have been used to investigate the
stresses experienced in the cement mantle  and to predict the life of
the cement mantle when taking different factors into account . The
number of elements used, or mesh density, is an important
consideration when creating a FE model. A model with an insufficient
mesh density will not be able to fully capture the stress state in the
area of interest, but increasing the mesh density dramatically increases
the computational cost of the analysis.
The aim of this study is to determine the mesh density necessary
to model creep and damage accumulation in the cement mantle of a
cemented implanted femur. We compare the initial stress state and
damage accumulation rate for different mesh densities and different
