Description
The paper presents the calibration of a numerical collapse model of
unidirectional fiberglass epoxy panels with an initially embedded
delamination. The panels were tested under axial compression, able to
induce buckling collapse. The penalty stiffness, the strength and the
fracture toughness are the key parameters governing the cohesive
interface. Their influence is investigated by a sensitivity analysis,
aimed at adjusting the cohesive properties in order to calibrate the FE
model based on the results of the experiments. The work serves as the
basis for a promising strategy aimed at improving the current numerical
models with progressive growing delaminations.
