| Abstract | ||||
| A shear thickening non-Newtonian fluid (STF) was prepared and studied for blast wave mitigation applications. STF was prepared by dispersing fumed silica (FS) particles with-in polyethylene glycol (PEG) by mechanical mixing. Average particle size of the dispersion was investigated by dynamic light scattering (DLS). A full rheological study was conducted with afterwards data processing to obtain governing equations for viscosity behavior over the thickening range using the non-Newtonian power law model. Blast threat was modulated using AUTODYN with further scaling to form better idea of equivalent threats. A numerical study was conducted using FLUENT con-cerning the blast loading attenuation capabilities of the prepared samples. Relatively high-loaded samples (10%, 15%) showed higher capabilities than other samples with the possibility of be-ing incorporated in composite systems to enhance their mitiga-tion abilities. | ||||
