Ninja
Ninja is a device designed specifically to perform rivet/fastener hole cold work validation.  Cold working creates a residual compressive stress near the hole boundary, thereby extending fatigue life by retarding crack formation.  Ninja quantitatively validates the cold work process by measuring the expansion magnitude.  Validation results are automatically recorded by Ninja in a detailed data log (CSV/Excel format).  Quantitative cold-work validation data can be used to assess task-completion and fatigue-life extension.  Ninja is a rugged device intended for harsh environments, and its simple 'wizard' style interface is tailored for use by artisans/technicians.
