つめの構造弾性率の測定と曲げ剛性について

抄録

In this study, based on the curved beam theory, the bending tests of fingernails were performed, and the structural elasticity of fingernails was determined. The determined value of the structural elasticity of fingernails was about 2.0 GPa. On the other hand, that of the manicured fingernails was about 0.9 GPa, and the manicured fingernail was found to have lower structural elasticity compared with the normal fingernail.
