Abstract
Most of the common methods for conducting fracture tests on adhesively bonded specimens refer to pure mode measures and to traditional load frames, where only one actuator is present. The critical strain energy release rates that characterize mode I, mode II and mixed-mode I/II fracture of bonded adherends can be measured also using a dual actuator load frame in which there are two degrees of freedom. The geometry that is tested is the double cantilever beam (DCB) type. DCB specimens are commonly used in traditional load frames for pure mode I tests but the independent actuators permit testing at different levels of mode-mixity. The focus of this paper is to develop and present evaluations of experimental and analytical aspects for mixed-mode fracture tests performed with the dual actuators liad frame. In fact, tests performed woth the dual actuator instead of other techniques give new possibilities and simplify the experimental effort, but also introduces different possible issues. New testing procedures have to be implemented; goals of these procedures are to enhance the capabilities of the dual actuator frmae maintaining some of the advantages of other techniques already in use woth traditional testing and analysis. Moreover, Nonlinear geometrical effects during the tests can play a role and are evaluated in this paper.
