Development of a mixed mode double cantilever beam specimen for the fracture characterization of adhesives under high displacement rate

In this paper, a new specimen called mixed mode double cantilever beam (MMDCB) was developed for the fracture characterization of adhesives under high displacement rates. The MMDCB designed using finite elements simulations in order to determine toughness mixity plane I+II+III. Firstly, results from specimens tested quasi-static loading were experimentally compared reference single leg bending test. test results, obtained with two different specimens, exhibit consistent evaluations toughness. Secondly, testing asymmetric rate validated through explicit simulations. corrected theory effective crack length extended analysis rate. It numerically proved accurately up 1 m/s.
