![]() ![]() ![]() There is a rapid increase in the use of carbon-fiber-reinforced composite materials in the aerospace industry over the last decade. The modeling of the impact zone with conical-shape geometry showed that the scattering directivity of the displacement field depends significantly on the size (depth and width) of the conical damage created during the point-impact of the composite with potential applications allowing the determination of the geometric characteristics of the impacted areas. ![]() The model was first validated by comparing the directivity of the scattered fields for the A 0 Lamb mode predicted numerically with the experimental measurements. The damage inside the plate is modeled as a conical-shaped geometry with decayed elastic stiffness properties. The 3D-FE frequency domain model is then used to simulate the scattering of an incident guided wave at a frequency below an A 1 cut-off with a wavelength comparable to the size of the damaged zone. Besides, barely visible impact damage of the desired energy was created and imaged using ultrasonic bulk waves in order to measure the size of the damage. In this work, we studied the scattering behavior of an incident A 0 guided wave mode propagating towards an impacted damaged zone created within a quasi-isotropic composite plate. The present paper deals with an effort to model impact damage in 3D-FE simulation. ![]()
