Comparison of Three Composite Failure Criteria, using Airfoil Loading Test

Regarding to the vast application of composite materials in the modern and advanced industries, accurately predicting the fracture and damage behavior of these materials is very important. Carrying out less and simple experiments leads to reducing the cost and time, therefore, designing and analyzing of the above mentioned materials need to find and applying the fracture and damage criteria. In the Iran country, these materials are more used for manufacturing the aircraft and for this reason, in this research airfoil piece is selected and simulated. For this aim, The Puck, Tsai-Wu, and Sun damage and fracture criteria are implemented into the ABAQUS commercial software, employing an implicit subroutine. After the simulation of the airfoil, the damaged zones and critical points of the airfoil are predicted by the three mentioned criteria, results of the numerical simulations are compared with the experimental results and validated. Comparison of the numerical and experimental results reveals that the predicted results of the Puck's damage criterion is closer to the practical results and is more reliable for predicting the damage in the airfoil loading test.
