The workings of the ultrasonic warning sounds produced by the wings of a species of moth have been revealed by researchers at the University of Bristol Composites Institute.
Structural buckling and sound production are rarely studied together, despite being reciprocal phenomena. In addition, buckling occurs as a sudden large deformation which can be attractive as a shape-changing mechanism in the field of morphing structures, such as in the aerospace industry, where engineers are looking to optimise the aerodynamic performance of wings.
