Special Issue Information

Dear Colleagues,

The mechanical properties of bone vary significantly within the bone body, since it is considered a heterogeneous material. Bone material properties are continually changing because of ageing, illness, nutrition, applied loads, and other factors. The characterization can be carried out at three levels, namely the macro-, micro-, and nanostructural levels, and considering several loading effects (static, dynamic, ...). The characterization can also be carried out considering several types of strategies—numerical and experimental or hybrid strategies. For example, numerical simulation, such as FEA, can be used to reduce the amount of measured data needed for prediction of the required models. In addition, optimization strategies can be utilized to find the best models for characterizing the bone material properties. Furthermore, uncertainty analysis can be performed on the resulting developed models to determine their confidence levels. In all these stages, sensitivity analysis can help to determine the effect of each input parameter on the studied output responses. The characterization of bone mechanical properties is necessary for many studies including prosthesis design, implant rehabilitation, and drilling surgery among many others. There is a strong need to provide new models, formulations, or strategies to improve these vital engineering applications for human healthcare objectives.

The fatigue damage behavior of bone has attracted significant attention in both the mechanical and orthopedic fields. However, due to the complex and hierarchical structure of bone, describing the damage process quantitively or qualitatively is still a significant challenge for researchers in this area. In this study, a nonlinear bi-modulus gradient model was proposed to quantify the neutral axis skewing under fatigue load in a four-point bending test. The digital image correlation technique was used to analyze the tensile and compressive strains during the fatigue process. The results showed that the compressive strain demonstrated an obvious two-stage ascending behavior, whereas the tensile strain revealed a slow upward progression during the fatigue process. Subsequently, a theoretical model was proposed to describe the degradation process of the elastic modulus and the movement of the neutral axis. The changes in the bone properties were determined using the FEM method based on the newly developed model. The results obtained from two different methods exhibited a good degree of consistency. The results obtained in this study are of help in terms of effectively exploring the damage evolution of the bone materials. Full article
