Multilayered plates have become a field of interest for vehicle lightweighting and improving survivability due to their variety of material and structural configurations. A new material to consider in multilayer plates is shear thickening fluids (STFs). STFs have been shown to improve the performance of body armor and to have structural damping applications. A new multilayer plate design is proposed in this dissertation that uses layers of STFs sandwiched between solid plate layers to act as a damping mechanism. The objective of this work is to investigate how STFs affect the dynamic response of a multilayer plate using computer modeling tools.A reduced order model in LS-DYNA was used to validate the significance of implementing a damping mechanism similar to an STF within a multilayer plate. Then a microscale model was developed in the computational fluid dynamics (CFD) program STAR-CCM+. This model used the discrete element method (DEM) to simulate the particles in the STF that are linked to its non-Newtonian behavior. The results of this microscale model were validated against published STF rheometry data. A macroscale model of the multilayer plate with layers of a STF was developed using the reverberation matrix method (RMM). The relationship between the shear rate and measured viscosity from the microscale results were input into the macroscale model. This multiscale modeling method was used to investigate how changing the material composition of a STF, such as particle size, affects the dynamic response of a multilayer plate. The results of these models indicate that incorporating the STF into a multilayer plate reduces its dynamic response.
