![]() ![]() It distributes the applied load and transfers it to the bone, reducing stress-shielding effects and prolong the bone-prosthesis system life span. The numerical result show that the carbon/PEEK composite material (configuration I) seems to be a good solution to increase the values of fatigue safety factor of coating layers due to highest fatigue life and fatigue safety factor. ![]() The carbon/PEEK composite material with 0, +45, -45, and 90 degrees fiber orientation (configuration I) has the highest fatigue life and fatigue safety factor. This shock absorbing effect may help to reduce damage and confer benefits such as improved comfort for these types of applications. In another study, the fatigue performance of PEEK was investigated under. In addition, PEEK has one excellent hydrolysis. No significant change in tensile properties was observed, but a decrease of 25 in fatigue strength was observed. The fatigue safety factor for the coated implant is increased more than 12.73% at least compared to the uncoated implant. PEEK is a relatively flexible material compared to the traditionally used stiffer metals (PEEK 4 GPa, titanium 105 GPa) and allows flex and stress transfer more like the natural properties of bone. The very good mechanical properties are also due to a excellent creep resistance and fatigue resistance approved. Fatigue life durations are calculated based on the Goodman mean-stress fatigue theory. The cyclic loads are applied on the prosthesis head. A 3D finite element models of hip implants, femur, coating layers with polymeric (PEEK) and composite (carbon/PEEK) coating materials are created for FEA. Yip M.C.,Tseng C.M.,&Tai N.H.(1998).Effects of cyclic thermal loadings on fatigue behavior of carbon/PEEK laminates.Key Engineering Materials(149 PART II),829-. A new crop of artificial intelligence tools carries the promise of streamlining tasks, improving efficiency and boosting productivity in the workplace. In the future, the fatigue strength of the novel materials could be. Compared to the two main methods used in. For the demonstration of printing parameter effects on the PLA fatigue lifetime. The authors have utilized a previously supplied dataset where different notch geometries in a physiologically relevant environment have been tested, revealing how PEEK fatigue behaviour is notch-sensitive. This study aims to validate, using finite element analysis (FEA), the design concept by comparing the fatigue behavior of hip implant stems coated with composite (carbon/PEEK) and polymeric (PEEK) coating materials corresponding to different human activities: standing up, normal walking and climbing stairs under dynamic loadings to find out which of all these models have a better performance in the prosthesis-bone systems. Herein this approach has been extended to the fatigue behaviour of PEEK, with satisfactory results. Polyetheretherketone (PEEK) material is a polycyclic, aromatic, thermoplastic polymer that is semi-crystalline and has a linear structure. ![]()
