## Description

- description: The local and global mechanical properties of a mineralized biological
    material using the mud crab as a model material were investigated and compared.
    The stress–strain (s–s) curves for wet and dry conditions of the endocuticle were
    exactly examined by performing tensile tests with strain gauges. The local properties
    were examined through nanoindentation testing (NI) in a dry condition. The global
    Young's modulus, E, evaluated from the slope of the linear part of the s–s curve,
    did not vary with wet or dry specimen conditions; however, the stress and strain
    required to fracture depended on the conditions. The E was compared with the results
    of property mapping obtained from NI. Due to local differences in the grade of
    mineralization in the exoskeleton, the mapping indicated that nanoindentation
    tests should be performed for an extensive region of the cuticle. The results
    will provide useful information for future material development based on biomimetics.
