| Abstract: | TA-XT2i texture analyser are used to test the tension mechanical property,elasticity degree and rheological property of the ventral scale on Burmese python,Zaocys dhumnades and Elaphe rufodoreata.The results indicate that the ventral scale material is viscoelastic material whose average elastic modulus is 1.5 GPa and fracture strength is less than 90 MPa.Among these three kind of snakes,elastic modulus of the ventral scale of Burmese python is highest,and Elaphe rufodoreata's is lowest.Ultimate strength of ... |
