... 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...

...Jonathan R. T. Jeffers; Martin Browne; Anne Roques; Mark Taylor Fatigue cracking in the cement mantle of total hip replacement has been identified as a possible cause of implant loosening. Retrieval studies and in vitro tests have found porosity in the cement may facilitate fatigue cracking...

... stain during the fatigue loading to observe directly the growth of individual cracks leading to trabecular fracture, we believe that it is likely that in some small fraction of the trabeculae, microcracks grow across the trabeculae, causing fracture. Finite-element models for fatigue crack propagation...

...D. A. Heuer; K. A. Mann A clamped cantilever beam test was developed to determine the fatigue crack propagation rate of the CoCr alloy/PMMA cement interface at high crack tip phase angles. A combination of finite element and experimental methods was used to determine the fatigue crack growth rates...
