152631 - Meso-Scale Modeling and Characterization of Polymer Matrix Inclusion Composite Ballistic Structures 

With the escalating threat of ballistic impacts, it is imperative to rigorously characterize the behavior of impacted structures under diverse threats. In recent days, studies have highlighted that dispersed inclusions within variable matrices can significantly enhance the robustness of composites, thereby improving ballistic performance. Building on this foundation, the current research delves into the intricate dynamics of projectile penetration and its subsequent effects on structures composed of different inclusion materials with variable size and volume fractions in distinct polymer matrices. Previous research work involved effectively characterizing the properties of polymer matrix sand composites (PMSCs) arranged in a graded configuration, with variations in inclusion size and volume fraction. Homogeneous computational models employing finite element analysis served as reliable predictors by incorporating variable material properties along the thickness. Expanding on these efforts, the current study introduces a comprehensive characterization through a mesoscale model that captures variations in inclusion size and volume fraction, enabling an advanced mesoscale analysis. The inclusions, ranging from metals to ceramics, are randomly dispersed within the polymer matrix to emulate real-world applications closely. The Heterogenous Impacted Structures study examines the influence of these variations on the erosion and ballistic resistance of the structure against projectiles with hemispherical and pointed-nosed tips. The mesoscale modeling reveals intricate phenomena such as bullet ricochet behavior, prolonged contact time, and reduced penetration depth, ultimately resulting in higher ballistic limits. Experimental impact studies further provide a broader prospect of the effects of gradation in a single-structure configuration, providing valuable insights into the optimization of ballistic-resistant materials.
