Influence of the third invariant in the ballistic impact of silicon carbide

► The JHB ceramic model is modified to account for the third stress invariant. ► Computed results are reported of ballistic impacts of silicon-carbide targets. ► Deep targets are relatively insensitive to the influence of the third invariant. ► Thin targets and compressive plate impacts are relatively sensitive. ► Plate impacts suggest the dependence of silicon carbide on the third invariant is strong.
