Abstract
- Transient deformations can be observed by means of time-resolved electronic speckle pattern interferometry (trESPI), which implements a high-speed camera in the experimental setup and allows measurements of non-reproducible transients in real time. The stick-slip phenomena in musical instruments leads to transient nonlinear effects in the surface deformation, which can be resolved and characterized using trESPI. In this work, transient effects during the stick-slip motion of the Brazilian cuica drum are investigated. Measurements of the cuica under harmonic excitation and in playing conditions using trESPI are presented leading to a quantitative analysis of the motion.
