Abstract

The selection between implicit and explicit finite element analysis has been the subject of many studies. Despite the fact that the implicit method is more reliable for dynamic analysis, convergence problems are the main cause of unrealistic simplifications. Although a few explicit simulations have been done on implanted knees, a comparison of dynamic implicit and explicit methods is still missing. The aim of this study is to compare dynamic implicit and explicit solutions in the analysis of a native knee joint, to investigate the convergence problem in the implicit method, and accuracy in the explicit method.
