Composite materials offer a unique combination of properties from lightweight and high strength to long-term durability and cost-effectiveness that opens the field for their application in different industries. However, under the application of an impact load, complex distribution of stresses and strains is produced in the composite. Researchers investigated different impact mitigation techniques like changing core designs to enhance load impact resistance and strength. Others examined fluid-filled barriers to mitigate the impact of ballistic loading by investigating the energy response and the energy absorption. In this research, the effect of filling a honeycomb core with water on its impact resistance and deformation behavior is examined. Numerical experiments were conducted using Abaqus/CAE software. Two different spacings for the core structure were examined. Results show that the water's ability to absorb kinetic energy resulted in a delay in damage initiation and propagation. Closer spacing between core-core structural elements increased the stiffness of the sandwich panel, improving its blast mitigation performance. [ABSTRACT FROM AUTHOR] |
