*2.1. Geometric Parameters and Material Properties*

The bearing geometry used for the current study was adopted from the research conducted by Jamari et al. [3] and is described in Table 1 for both the femoral head and the acetabular cup, which are commonly used in total hip arthroplasty.

The properties of metallic materials evaluated in the current study were based on previous studies: CoCrMo from Jamari et al. [3] and SS 316L and Ti6Al4V from Jiang et al. [11], which are described in Table 2. All simulated materials are assumed to be homogeneous, isotropic, and linear elastic.

**Table 2.** Material properties for metallic materials.


To consider the surface roughness during articulation in metal-on-metal bearings, the coefficient of friction is given for the current computational simulations described in Table 3. The coefficient values for various metal-on-metal bearings were adopted from the previous literature: CoCrMo-on-CoCrMo from Jamari et al. [3], SS 316L-on-SS 316L from Jin et al. [12], and Ti6Al4V-on-Ti6Al4V from Arash et al. [13].
