A new testing device to simultaneously measure the mode I fatigue delamination behavior of a batch of specimens

• A test device and a method to run 6 DCB fatigue tests in parallel are detailed. • The method allows testing at different levels of energy release rate and load ratios. • Onset of fatigue propagation of 6 DCB specimens is determined in one run. • Continuous crack growth rate curves are obtained. •...

• A test device and a method to run 6 DCB fatigue tests in parallel are detailed. • The method allows testing at different levels of energy release rate and load ratios. • Onset of fatigue propagation of 6 DCB specimens is determined in one run. • Continuous crack growth rate curves are obtained. • The onset points are determined with an accuracy of 1 cycle.
