摘      要：Beetle wings are very specialized flight organs consisting of the veins and *** it is necessary from a bionic view to investigate the material properties of a beetle wing *** the present study,we have used a Digital Image Correlation (DIC) technique to measure the elastic modulus of a beetle wing *** were prepared by carefully cutting a beetle hind wing into 3.0 mm by 7.0 mm segments (the gage length was 5 mm).We used a scanning electron microscope for a precise measurement of the thickness of the beetle wing *** specimen was attached to a designed fixture to induce a uniform displacement by means of a *** used an ARAMISTM system based on the digital image correlation technique to measure the corresponding displacement of a *** thickness of the beetle wing varied at different points of the *** elastic modulus differed in relation to the membrane arrangement showing a structural anisotropy;the elastic modulus in the chordwise direction is approximately 2.65 GPa,which is three times larger than the elastic modulus in the spanwise direction of 0.84 *** a result,the digital image correlation-based ARAMIS system was suc- cessfully used to measure the elastic modulus of a beetle *** addition to membrane s elastic modulus,we considered the Poisson s ratio of the membrane and measured the elastic modulus of a vein using an Instron universal tensile *** result reveals the Poisson s ratio is nearly zero and the elastic modulus of a vein is about 11 GPa.
