Abstract
In this research, a novel data reduction method for calculation of the strain energy release rate (SERR) of asymmetric double cantilever beams (ADCB) is presented. For this purpose the elastic beam theory (EBT) is modified and the new method is called as the modified elastic beam theory (MEBT). Also, the ADCB specimens are modeled using ABAQUS/Standard software. Then, the initiation of delamination of ADCB specimens is modeled using the virtual crack closure technique (VCCT). Furthermore, magnitudes of the SERR for different samples are also calculated by an available data reduction method, called modified beam theory (MBT). Using the hand lay-up method, different laminated composite samples are manufactured by E-glass/epoxy unidirectional plies. In order to measure the SERR, all samples are tested using an experimental setup. The results determined by the new data reduction method (MEBT) show good agreements with the results of the VCCT and the MBT.
