| Abstract [eng] |
The aim of the present work is to compare the in-terlaminar shear strength and fracture toughness of glued carbon fiber rods obtained using different experimental ap-proaches and provide the effective way to characterise the interlaminar properties for reliable simulation of the delam-ination. Five different test methods (tension, single shear test, and double shear test, mode I and mode II delamination tests) were performed. Using the explicit LS-DYNA code the finite element model capable of simulating the damage process of bonded connection was developed. The interlam-inar connection and delamination criteria were calibrated using the parameter identification methodology imple-mented in LS-OPT optimization tool. |
