Civilian evaluation kit for shock/vibe peak-load reduction + SHM skin diagnostics. Defines falsifiable claims/non-claims, failure modes, calibration gates, audit-grade logging, and scripts to validate runs and reproduce metrics—built for structures/test engineers to prove or kill fast.

Modal identification of a base-excited SDOF oscillator using RK4 time integration, transmissibility (FRF) sweep, half-power damping estimate, and FFT analysis.
