Resumo: | Fracture of bone in vivo generally occurs as a result of multiaxial loaded conditions, which leads to complex mixed-mode stress-states involving the combination of tension, compression and shear. As a result of this the characterization of the mixed-mode crack propagation assumes a high level of importance. In this work we analysed the adequacy of a miniaturized version of the single leg bending test (SLB) to characterize the mixed-mode I+II fracture behaviour of young bovine bone tissue. Hence, a new data reduction scheme based on specimen compliance and crack equivalent concept was used to overcome the difficulties inherent to crack monitoring during its growth. The method was applied to the experimental results in order to obtain the Resistance-curves in each mode. It was concluded that the developed version of SLB test is adequate for mixed-mode fracture characterization of bone, since it permits to obtain a complete Resistance-curve though revealing an almost constant mode ratio. |
