Keyword: PEEK 3D printing Cellular CHAp Biomaterial Bone implant. For the first time, we aim to provide such a criterion employing an energy-based approach, i.e., the strain energy density (SED) criterion. This process is experimental and the keywords may be updated as the learning algorithm improves. This criterion should not only predict the tensile behavior independent from type of PEEK base material and geometry, but should also account for degradation effects due to environmental impacts. These keywords were added by machine and not by the authors. ![]() ![]() It is concluded that crack closure effects are probably more significant for this material. ![]() For the higher fibre content material, the models employed are less accurate. These are reasonably successful for the lower fibre content composite, suggesting that static effects may be interacting with cyclic modes during fatigue failure at higher mean stresses. Polyether ether ketone (PEEK) is a material that has gained. In contrast, the titanium abutments concentrated the plastic deformation at the internal connection of the dental implant. Applying two models which are modifications of the Paris law, attempts have been made to rationalise the effects of mean stress on fatigue crack propagation in these materials. The properties of materials are constantly being enhanced, and new products are being introduced. Analysis of crack growth data using the Paris law indicates significant variations for both materials as stress ratio R is raised from 0.1 to 0.5. The effects of mean stress/stress ratio on fatigue crack propagation have been investigated for two volume fractions of short carbon fibres in a PEEK matrix. ![]()
