Abstract

This paper reports finite element multi-scale simulations of ballistic impact damage of three-dimensional angle-interlock woven composite (3DAWC) penetrated under a hemispherical rigid projectile. A multi-scale geometrical model of the 3DAWC was established for the numerical simulation. The multi-scale geometrical model of the 3DAWC consists two parts: one is the microstructure model and another is the continuum model. The microstructure model has the same microstructure with that of the 3DAWC composite panel, including the fiber tows' diameter, fiber tow configuration and fiber volume fraction. The continuum model has the same mechanical properties with the 3DAWC. The commercial-available finite element software package Ls-Dyna was used for the ballistic penetration damage simulations. The ballistic impact damages of the 3DAWC and the residual velocities of the rigid projectile under the different strike velocities have been calculated and compared with those in experimental. Good agreements were found between the finite element analyses (FEA) and experimental. From the FEA results, the impact damage development and the stress wave propagation in the 3DAWC panel can be extracted to find the influence of the microstructure parameters of the 3DAWC on the ballistic impact capacity. With the efforts, the ballistic impact capacity of the 3DAWC could be designed in a more precise way.
