“…Following Equation (2), the equivalent fatigue life, N f(eq) can be written as; where σ a(0) is the reference stress amplitude at which equivalent fatigue life is to be calculated. In past studies on fatigue crack growth rate in bone cement [33-42], values of m were reported to be between 3.60 and 18.20. Therefore, Wilcoxon hypothesis tests were conducted with m values varying between 3.5 and 19.0 for σ a(0) = 15.0 MPa.…”

Fatigue life of Simplex P bone cement was tested at three different stress amplitudes by using specimens produced by two different mixers. Fatigue life data showed high variability in all instances. Statistical analysis showed that fatigue life was not affected by the type of mixer. Analysis of fracture surfaces showed that fatigue life variability could be attributed to the presence of defects, such as bubbles and mixing defects. Both Weibull and Tiryakioğlu distributions provided excellent fits to the fatigue life data. Moreover, the Gumbel parameters for fatigue initiator size data estimated in the Tiryakioğlu distribution agreed closely with fractographic measurements.

“…They used the data of five specimens to generate a single regression line described by Paris' law, obtaining a general coefficient of regression of 0.96. Two different PMMAs, rather than PMMA based bone cement, were tested by Hao et al [11] using both compact tension (CT) and middle tension (MT) fracture toughness samples. Using CT samples they found that there was minimal differences between the two cements, but using the MT there was an obvious difference in the gradients of the / versus ∆ graphs, thus indicating difference in the Paris Law equations.…”

Poly(methyl methacrylate) (PMMA) bone cement is used to anchor the majority of total joint replacements (TJRs). Many brands of cement are used, both with and without the addition of antibiotics to reduce the risk of infection. The present study involved determination of various parameters in tensile fatigue loading: 1) energy absorbed (U) vs number of loading cycles (N) and creep strain (e) vs N, during fatigue tests on specimens of an antibiotic-containing cement (SmartSet GHV) and a plain cement (CMW1) and 2) crack length (a) vs fatigue loading cycles (N) and crack growth rate (da/dN) vs Mode I stress intensity factor range (DKI), during Fatigue Crack Propagation (FCP) tests. In the fatigue tests, four different sample types (round, machined; round, directly moulded; rectangular, machined, and rectangular, directly moulded) and tensiontension loading were used. In the FCP tests, compact tension specimens under tension-tension loading were used. It was found that there were limited effects of sample type, except at the highest stress levels, but that these two cements had different rates of crack propagation. These differences were reflected in the fracture surfaces with SmartSet GHV showing accumulation of opacifier around the particles and crack progression around the intial beads, while for CMW1 the opacifier was evenly distributed and the cracks went through the initial beads.
