Abstract
This study investigates the vibration behavior of adhesively bonded composite cantilevers composed of two beech wood lamellae and a bondline made of various flexible polyurethane adhesives. While all cantilevers had constant height and cross-sectional dimensions, they differed in the thickness of their adhesive layers. To comprehensively assess the dynamic characteristics of the specimens, two experimental approaches were employed: the inertance function in the small-strain domain, and the sweep load response for large strains.
