| Abstract Scope |
We explore the dynamic deformation mechanisms in SS316–A356 interpenetrating composites subjected to high-strain-rate compression using the Split Hopkinson Pressure Bar (SHPB) technique. The PrintCast method was used to create composite structures that enable the manufacturing of complex intrinsic designs. We emphasize the design of mesoscale structures specifically engineered to induce controlled shear deformation by manipulating the lattice geometry and volume fraction. Our investigation combines numerical simulations with experimental validations, using the Johnson-Cook (JC) constitutive model to compare the predicted structural behavior with the actual responses observed in physical systems. By utilizing computational design and numerical analysis of structures, we can streamline the production process and reduce the number of candidate structures. This method opens the opportunity for precise manipulation of mechanical properties. By integrating experimental, post-mortem, computational, and data-driven approaches, we explore a new systematic framework to gain insight into shear deformation mechanisms under conditions of high-strain loading. |
