We experimentally investigate the growth dynamics of cavities nucleatingduring the first stages of debonding of three different model adhesives. Thematerial properties of these adhesives range from a more liquid-like materialto a soft viscoelastic solid and are carefully characterized by small strainoscillatory shear rheology as well as large strain uniaxial extension. Thedebonding experiments are performed on a probe tack set-up. Using high contrastimages of the debonding process and precise image analysis tools we quantifythe total projected area of the cavities, the average cavity shape and growthrate and link these observations to the material properties. These measurementsare then used to access corrected effective stress and strain curves that canbe directly compared to the results from the uniaxial extension.
