This theoretical study analyzes the possibility to use the classical Mott's hypothesis to model the natural fragmentation of cylindrical structures with two or more metal cylinders arranged coaxially. A critical analysis on the validity of the used hypothesis was conducted based on empirical relations and numerical simulations. The established algorithm allows the determination of a fragment mass scale parameter for each individual cylinder, which is why the cumulative distribution of fragments for the entire structure may be calculated.

- The study introduces a new, cost-effective method for creating polyurea-polyurethane nanocomposites enhanced with multiwall carbon nanotubes (MWCNTs), which show improved mechanical properties.
- Characterization techniques such as SEM and micro-CT confirm the uniform dispersion of MWCNTs within the polymer matrix, and various experimental tests indicate significant enhancements in thermal and mechanical performance.
- Impact tests demonstrate that these nanocomposites can greatly improve the ballistic protection of aluminum plates, allowing them to withstand forces nearly 200% stronger than uncoated metal plates.
