Abstract

In the present study, a digital image correlation method has been applied to measure the elastic modulus of a beetle wing membrane. Specimens were prepared by cutting beetle wing carefully with a size of 3.0 mm in width and 5.0 mm in length. We used a scanning electron microscope for exactly measuring the membrane thickness of a beetle wing membrane. The specimen was attached to a designed fixture to induce a uniform displacement using a micromanipulator. We measured the applied load and the corresponding displacement by a load cell with a maximum capacity of 5 N and by an ARAMIS system based on the digital image correlation method respectively. The measured thickness of a beetle wing varied from point to point of the wing part and the elastic modulus was different according to the loading direction. In conclusion, we successfully measured the elastic modulus of a beetle wing with an ARAMIS system based on the digital image correlation method.
