The effects of static, dynamic and fatigue behavior on three-dimensional shape optimization of hip prosthesis by finite element method

Femoral hip prosthesis design for Thais using multi-objective shape optimization

“…All contacts are assumed to be completely bonded. From this point, all volumes of the prosthesis, cement and cortical bone are meshed using the material properties shown in Table 1 [12,26]. The element type used is a 4-node tetrahedral, SOLID285.…”

“…For example, Katoozian et al [11] introduced three-dimensional shape optimization of a femoral prosthesis in which the geometry was defined in terms of longitudinal and cross-sectional shape variables. Kayabasi et al [9,12,13] and Tanino et al [14] followed a similar approach but with different objective functions. Kayabasi's study used maximum von Mises stress of a femoral prosthesis as an objective function to minimize while Tanino's study used the cement's maximum von Mises stress as an objective function.…”

Fatigue design of a mechanically biocompatible lattice for a proof-of-concept femoral stem

“…In literature, there are several experimental and numerical studies focusing on the fatigue analysis of hip implants (Baleani et al, 1999;Hedia et al, 1996;Kayabasi and Ekici, 2007;Li et al, 2002;Nganbe et al, 2011;Ploeg et al, 2009;Raimondi and Pietrabissa, 1999;Senalp et al, 2007). For 3 example, fatigue loading conditions, ISO 7206/3, have been applied to a hip stem to predict its elastic stress via large deflection finite element analysis (Ploeg et al, 2009).…”

“…It has been demonstrated via experiments that the high cycle fatigue-life of hip stems can be adequately predicted by using alternative fatigue theories, such as Morrow, Smith-Watson-Topper (SWT), and Goodman. The Soderberg theory has also been used to design a cemented implant for infinite life; the results have been proved to be accurate although more conservative than those obtained with Goodman and Gerber theories (Hedia et al, 1996;Kayabasi and Ekici, 2007).…”

Mechanical and functional assessment of the wrist affected by rheumatoid arthritis: A finite element analysis

“…The use of finite element analysis has been demonstrated to be a reliable tool for investigative purpose [9][10][11][12][13][14][15][16][17][18] and may be appropriate to determine the changes involved in RA. This method has also been widely employed due to its ability to simulate load distribution and deformation patterns which, cannot be reliably achieved using any other methods [19][20][21].…”
