Numerical simulations have provided option to reduce the number of experimental studies through analysis of different hip implant surface topographies. However, this approach takes time as there are different model parameters that should be considered in order to understand how they affect the obtained shear stress values. The use of classification algorithms is an approach that could reduce the time required for simulation by providing information about models with biggest potential. Eleven model parameters related to model and surface topography were considered in combination with four classification algorithms &#8211; Support Vector Machines (SVM), K &#8211; Nearest Neighbor (KNN), Decision Tree (DT), and Random Forest (RF). The considered parameters were: Number of half-cylinders lengthwise (&gt;0); Number of half-cylinder rows (\u22650); Half cylinders added or removed from the surface (0 \u2013 removed; 1 &#8211; added); Distance between half-cylinders lengthwise (\u22650); Distance between half-cylinders widthwise (\u22650); Number of different radius values (1 or 2); Radius 1 value (&gt;0); Radius 2 value (\u22650); Distance from the edge where loading is located (\u22650); Distance from the other edge of the model (\u22650); Model includes trabecular bone (0 \u2013 not included; 1 &#8211; included). The aim was to apply previously mentioned algorithms to obtain information if the maximum shear stress value was above or below user-defined threshold. The obtained results show that this approach can be useful to obtain preliminary information about models that should be numerically analyzed. <\/p>\n\n\n\n<p class=\"abstract-para\"><strong>Keywords:<\/strong> classification, finite element analysis, hip implant, surface topographies <\/p>\n\n\n\n<p class=\"abstract-para\"><strong>Acknowledgement:<\/strong> This research is supported by the European Union\u2019s Horizon 2020 research and innovation programme under grant agreement No. 952603 &#8211; SGABU.
