Abstract
The quadrupole method has been shown as a viable technique for rapid three-dimensional thermographic simulations of a delamination. Previous efforts have focused on the simulation of a single delamination in a composite. Realistic impact damage in composites is typically multiple overlapping delaminations at different depths. The quadrupole method is expanded to enable rapid simulation of multiple overlapping delaminations at different depths. Quadrupole simulations are performed by incorporating x-ray computed tomography information on the depth, shape and contact resistance of impact induced delaminations. The simulation results are compared to thermographic measurements on the impacted composite.
