Dataset description
This dataset contains the full set of output values from a modelling study, summarised as follows. An important aspect in evaluating the resilience of hip replacement designs is testing their performance under adverse conditions that cause edge loading of the acetabular liner. The representation of edge loading conditions in computational models is computationally challenging, however, due to the changing contact locations, need for mesh refinement, and dynamic nature of the system.
In the associated paper, an initial starting point for finite element modelling of this type of testing was developed. This consisted of recommendations for aspects such as the element type and shape, and to set up the head as the translating component and fix the liner using boundary conditions. It also included recommendations for element sizing for the bulk of the liner and the contacted rim, and a mass-scaling target time increment for the elements of the liner. In the paper we present a relatively clean sensitivity study to justify these choices and describe the sensitivity of results around them so that someone putting together a new model can hopefully do so far more quickly. There was a large amount of underpinning sensitivity testing, however, which was less structured but important for getting to this final recommendation. This data packet therefore contains results from two preliminary load cases (A and B) as well as the data used in the supported paper (case C).
