Materials Letters, 97, 166-168. | Series/Report no.: | Materials letters | Abstract: | The material property of the leading edge vein (LEV) of the dragonfly wing is investigated. A new vibration method is developed using a laser vibrometer and mini-shaker. The natural frequency of a cantilevered LEV is determined via lateral oscillation. As a result, the elastic modulus of a LEV sample from a dragonfly wing is found to be in the range of the elastic hydrocarbon polymer, while a dead dragonfly is similar to low density polyethylene. The loss of water contents in the veins increases the stiffness of the LEV by approximately 20 times. | URI: | https://hdl.handle.net/10356/85658 http://hdl.handle.net/10220/12974 |
