Abstract: | The skeleton is a multiscale hierarchical structure composed of minerals, collagen proteins, and
other constituents. The complex non-uniformity and anisotropy of bones are attributed to their adaptive
characteristics under physiological loads. To characterize the biomechanical properties of bones in various
fields such as mechanical engineering, biomechanics, medicine, aerospace, and forensics, it is necessary to
employ a range of material testing methods to accurately obtain the material constitutive parameters of the
skeleton. The article comprehensively introduces the preservation, preparation, testing, and identification
methods for material constitutive parameters of bone specimens, and analyzes the characteristics of various
mechanical testing methods and their requirements for bone samples. Additionally, the article discusses the
application of new testing technologies in characterizing the biomechanical properties of bones. Finally,
based on the three-point bending testing method, this article proposes a process for acquiring material
parameters of human bones. The methods and technologies discussed provide theoretical and methodological
references for the systematic characterization of bone biomechanical properties. |
