... to a polymethylmethacrylate (PMMA) bone cement led to detrimental effects on various mechanical properties of the cement such as bending strength, compressive strength and fracture toughness (K IC ). This finding implied that the mechanical failure of antibiotic-loaded PMMA bone cement was influenced by its pore volume...

... consists of cortical bone and other half of the width was cancellous bone; this interfacial bone is referred as a corticellous bone. Elastic–plastic fracture mechanics was used to measure fracture toughness. The J integral (both elastic and plastic) was used to quantify the fracture toughness. The plastic...

... impact on dynamic behavior of materials, primarily due to the inertial effect. Experiments conducted in Ref. 58 59 60 61 revealed many characteristics of dynamic fracture under different loading rates. In particular, they found that the dynamic fracture toughness increases when a crack accelerates...

..., with the combined effect of 4% increase in porosity and decrease in the cohesive properties reflecting other age-related changes in bone. These results show that intracortical porosity is a significant contributor to the fracture toughness of the cortical bone and that the combination of computational modeling...

... tensile, plane strain fracture toughness, and fatigue crack propagation rate tests were performed on both the third- and fourth-generation composite material formulations using standard ASTM test techniques. Injection molding techniques were used to create random fiber orientation in all test specimens...

... properties of the manatee ribs need to be better understood. Fracture toughness ( K C ) has been shown to be a good index to assess the mechanical performance of bone. Quantitative fractography can be used in concert with fracture mechanics equations to identify fracture initiating defects∕cracks...

...D. J. Adams; K. M. Brosche; J. L. Lewis Fracture toughness and crack tip opening angle were measured for bovine patellar cartilage using modified single-edged notch specimens of two thicknesses. There was no difference in fracture toughness between thin (0.7 mm) versus relatively thick (2.7 mm...
